This is a show that could rightly be considered the father of sci-fi television series. It was the first show to chain events together into a string of continuity. Every episode fed into the next one, creating a single story that ends in a climactic season finale. The crew of the Jupiter 2 often fought and were at odds with each other, conflicting attitudes and values between the Robinson family, Major West, and Dr Smith.
The show introduced mystery and explored strange new environments on a regular basis, and seldom if ever was everything tied up in a bow at the end of the episode. Much of what the crew endured was left to the imagination of the audience. The show dealt with moral and scientific problems on a regular basis without the heavy-handed commentary of later sci-fi.
If a valid criticism were leveled at it, I might suggest that the acting and effect are very much a product of the 60s. The pacing and filming choices are likely to seem odd to a modern viewer.
I really like this show. Anyone share the love?
