This review is based on seasons 1 and 2. The show differs from a lot of other Science fiction shows out there and it is a good thing. Instead of pushing the bleak and depressing aspects of a dystopian future like most Science Fiction shows do, this one is a glass half full. Although the Robinson family are constantly in peril, the focus is on keeping the hope and muddling through by banding together as a team, which makes great family viewing. The characters have a lot to deal with; killer robots, harsh enviromental factors, and a healthy dose of weird alien creatures. There is never a shortage of danger which keeps the pace flowing and keeps it exciting. The visual effects and musical score are top notch making the show's world very immersive, and the actors do a pretty good job of bringing the characters to life. The main plot could have been more fleshed out or prominent, but the show's episodic nature did a good job of holding my attention throughout. Overall a very entertaining show.
