Tv Season Info

"When am I?" John Locke's chronological confusion sums up Season 5, which hopscotches dizzyingly between the 1970s and 2007 as it charts the Oceanic Six's return to the island and reveals important island secrets. On the island, Locke (Terry O'Quinn) is the new leader of the Others. But in L.A., he's dead, and his death plays a key role in getting Jack (Matthew Fox), Kate (Evangeline Lilly), Hurley (Jorge Garcia) and Sun (Yunjin Kim) to return via Ajira Airways. Sayid (Naveen Andrews) refuses to join his fellow former castaways, but winds up being escorted onto the Guam-bound flight by a bounty hunter named Ilana (Zuleikha Robinson). Ben (Michael Emerson) must return, too, to face judgment for allowing his daughter Alex to die. Their flight---with Frank Lapidus (Jeff Fahey) at the controls---is a bumpy one, but the final destination is indeed the island. Ben, Sun, Ilana and Frank remain fixed in time upon their return to the island, but Jack, Kate, Hurley and Sayid are flashed back in time to 1977, where they are reunited with Sawyer (Josh Holloway) and Juliet (Elizabeth Mitchell). After surviving a series of time-travel flashes, Sawyer and Juliet landed in the 1970s and forged a close relationship with each other and the Dharma Initiative, which also welcomes Miles Straume (Ken Leung). Meanwhile, Miles' colleague Daniel Faraday (Jeremy Davies) embarks on a time-traveling mission that introduces him to a nuclear bomb named Jughead and a young woman named Ellie. Both play prominent roles as the season progresses.

If you're a fan, you'll be rewarded with richly intertwined and well-acted drama.

The genius of "Lost" is that it has much to offer both to the fans who can't wait for the smoke monster's next visit and those who prefer more human concerns.

Jan 21, 2009 | Full Review…

I continue to feel confident that "Lost" executive producers Carlton Cuse and Damon Lindelof know precisely what they are doing with this six-season global adventure.

The good news is, even if certain events seem fated to occur (and re-occur), even if some are fated to destroy themselves, personal redemption is possible, "Lost" appears to be saying.

Over the five seasons of Lost, loyal viewers have surrendered to the addictive, maddening mystery.

If Season Five has taught me anything about Lost, it's not to assume anything.

Talk about a skipping record -- we've definitely heard that before.

While light on island mythology, this episode of Lost was heavy on Miles. Considering the mysterious, entertaining character he's grown into, this was far from a bad thing.

Nothing prepared us for two of the bombshells dropped out of nowhere in the last five minutes.

May 29, 2018 | Full Review…

Season 5 of Lost does an exceptional job of building on the story told in the past four seasons.

May 29, 2018 | Rating: 8.6/10 | Full Review…

With an end date in sight, Lost remains compelling television. And we just have to have confidence that the writers know what they're doing.

Jun 5, 2014 | Full Review…

It's the characters in the show and their stories that make the series worth watching, especially for those of us who sometimes feel a bit lost when we're watching Lost.

Audience Reviews for Lost: Season 5

  • Oct 15, 2020
    The greatest mind bending season of TV I have ever seen.
  • Jul 25, 2020
    The wheels are off the plane at this point. Story twists that are attempting to shock rather than help the story. Great characters thrown away for no reason and a mystery that amperes like it will never resolve.

    Get ready to be confused newcomer! I'm so glad my first time watching was with someone else so that they could explain to me how the time-travel works in this show. It's so confusingggggg..... Butttttt, Lost season 5 was consistent with the fact that every episode kept you on the edge of your seat, wondering what was going to happen next (But that might be because a good chunk of it takes place in the past, which makes it fascinating). It works well by showing us 1977 and the present! You have so many questions that you know the show has to answer, and they do! I downgraded it to 4 stars for being confusing and watching the characters make kinda stupid decisions.

    You know how you can really tell if a show is good? You rewatch it every other year and make others watch it with you just so you can talk about it with them lol... Yes I do that :P
  • Dec 28, 2018
    Although the sci-fi aspect of this season slightly outshines its brighter moments, season 5 is still one of the most binge-worthy in television.
  • Nov 04, 2018
    Cuse e Abrams disseram que "eles ainda poderiam estragar tudo". Mas eu não me importaria, porque o a série deu tantas reviravoltas deslumbrantes e "whoppers" dramáticos. Uma das melhores temporadas de 2009, sem dúvida.
  • Aug 26, 2018
    Season 5's introduction of new questions made it not as good as Season 4, but I can praise it for its story and twists "Lost" is known for.
  • Mar 05, 2017
    The Fifth Season of LOST was the first one I watched live from beginning to end. It is also the most intricately plotted season of the show, and really branches it off into entirely new dimensions (almost quite literally!). Those two things did not mesh well upon my first go-round with the season (spring of 2009). When having to wait week-to-week for each episode, and then being promised seemingly "all the answers" by the ABC promos each week, I always considered S5 to be perhaps the weakest season of the bunch. During my recent re-watch of the show, however, this actually became the season I was most wrong about. Season Five might just be the best of them all. What needs to be understood about LOST is this: Seasons 1-3 are basically a separate show from what succeeds it. That portion of the series is mostly about a group of plane-crash survivors trying to get off an island and back to civilization. Sure, the island itself is full of mystery, but the driving force behind everything is a desire to be rescued. Season Four starts to change that narrative (and I would argue does so a bit erratically), and Season Five cements it in place. By this point, the show is no longer primarily a survival drama (even though it still is top-notch at handling its large ensemble cast). Now, it is a full-blown science fiction romp, complete with time paradoxes, body-swapping, and multiple timelines. I know a number of people who sort of melted away from watching the show during this season, and I strongly believe this change to be the reason why. For me, the change was incredibly exciting (and I'll argue also necessary to avoid stagnation) and stretched the show in ways it hadn't even attempted before. I won't go into any major spoilers here, but Season Five deals in many different time periods. In the first few episodes, those left behind on the island find themselves skipping through time (thanks to Ben's turning of the wheel), while those in Los Angeles struggle to decide if heading back to the island is the correct decision to make. Once everything shakes out in those two scenarios, it is an absolutely brilliant idea to show the inner workings of the DHARMA Initiative by actually placing some of the castaways within it! All the scraps about DHARMA that viewers had been given in seasons 1-3 are able to be seen first-hand, and it is wonderful. The finale episode? Perhaps the best in show history, resolving both the DHARMA goings-on and completely blowing the doors wide open by introducing the mysterious, oft-mentioned Jacob and the equally enigmatic "Man in Black". Not since S1 has this show been able to meld character elements with perfectly-paced plot lines as it did here in S5. As exciting and mind-bending as the time aspects are, it is equally as dramatic to see our favorite characters struggle to come to terms with being scattered to the winds of time, as it were. The mid-season episode "LaFleur", for example, is every bit as emotional as S4's "The Constant" in terms of emotional character development. One final interesting note: When show creators Damon Lindelof & Carleton Cuse were negotiating with ABC for an end date to the show, they originally said five seasons. ABC countered with something like 8, and they eventually settled on six. That original "five seasons" proposal makes a lot of sense to me now, as to be totally honest I think that seasons 4 and 5 of this show could honestly have been combined to make one "super-season". In a number of cases, I felt like similar material was being covered, and I truly believe that S5 did it in a better fashion. Not saying that S4 is poor by any means, but I think some of its inconsistencies are smoothed out by the storytelling here. Overall, then, S5 may be my favorite season of this entire show (with Season 1 being its main challenger). Both seasons are similar in the sense that all their aspects are woven so perfectly together. Whereas seasons 2-4 charge here and there full-bore into many different angles, seasons 1 & 5 are a bit more masterfully created (episode-by-episode) to hold up on even that micro-level. As long as you can accept that by this point LOST is no longer "Jack leading a group of survivors" and are willing to open yourself up to new storytelling possibilities, this slate of episodes will almost leave you speechless.

    Best season with the Faraday connection added to make the show solid where loose ends were developing in past seasons.

    Leaves you questioning and wanting more. You definitely become invested in the characters.
