"Danger, Will Robinson!" The rest of the Robinson clan should be on the lookout for danger, as well, because they are facing challenging times. It's 30 years in the future and the family has been chosen to start a new life in a space colony. On the way to what they believe will be a better world, the Robinsons' ship is abruptly thrown off course and they are thrown into a dangerous alien environment. Now light-years from their original destination, they must forge new alliances and work together to survive. Stranded with the Robinsons are unsettlingly charismatic Dr. Smith and inadvertently charming Don West, two outsiders who are thrown together by circumstance and a mutual knack for deception.

Dan Gentile San Francisco Chronicle 12/14/2021
The secret sauce to the Robinsons' success, and why the show has such an appeal beyond hard sci-fi fanatics, is the family bond. Go to Full Review Aaron Phillips But Why Tho? A Geek Community 01/23/2023
8/10
It’s difficult to hone in on what makes Lost in Space Season 3 so bloody enjoyable without feeling the need to retrospectively look back at the past three seasons now that it’s all over. We’ve watched these actors grow over the years. Go to Full Review Alci Rengifo Entertainment Voice 12/08/2021
Lost in Space was and is more than another zoom across space and time. Go to Full Review Austin Burke Austin Burke/Flick Fan Nation 12/01/2021
8.5/10
The final season raises the stakes and delivers the best batch of episodes yet. The character moments are much improved, but the technical elements of this series should be talked about more. Fans will love this finale. Go to Full Review Dylan Roth Polygon 12/01/2021

Devon K @Cloneux Jul 7 I think this Season may have slowed a bit in comparison to the second season, but they were equally as good, great drama and tension through the season, and some heartfelt moments. A strong ending to a great show. See more Sankalp good S @Sanna Jun 30 3x absolute fantastic epic satisfying best season n best conclusion love it 💖💫🦸‍♂️👏🎉👌 See more John D @RobDoe Mar 21 The production values are high. The problem is the terrible story telling. The show lurches from one contrived situation to another where the leads are protected by plot armor. The basic premise of robots that are required for interstellar travel is silly and story goes down from there. See more Len P 02/14/2025 The Dr Smith subplot became a little less ridiculous by season 3 but the robot subplot became even more ridiculous, erratic and illogical. Script writers scrambling for a storyline as they run out of ideas. I watched all episodes of 3 seasons. Lots of wasted boring screenplay on bland character interactions to pad out the episodes. I had to hit the 10 second fast forward in so many scenes, as the corny cliche character interactions were driving me nuts A hint of further episodes in the series which I will not be watching. See more Gerald A 06/25/2024 Visual effects are good but the plot armor of the Robinsons is not for me See more Andy L 09/09/2023 I loved this final season and am bummed we don't get to see more of Alpha Centauri. I love the aesthetics of the colony and seeing the beauty of a new planet serving as a fresh start for humanity. See more Read all reviews
