"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.

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? Jan 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 Dec 8, 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 Dec 1, 2021

See more TheCookieLord T @RT15771999 May 29, 2026 It was so good I miss it already. A must watch. See more Marco L @decatur555 Mar 5, 2026 A solid modern reboot of the classic sci-fi adventure. Lost in Space impresses with strong visual effects and an engaging sense of exploration, even if the plot sometimes overcomplicates itself. The family dynamic keeps the story grounded, making it an entertaining and accessible space adventure. See more Devon K @Cloneux Jul 7, 2025 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, 2025 3x absolute fantastic epic satisfying best season n best conclusion love it 💖💫🦸‍♂️👏🎉👌 See more Read all reviews
