I don't know how it gets worse than this. I am the world's biggest fan of Lost In Space, but really... talking carrots? After watching The Great Vegetable Rebellion, I didn't eat carrots for two years! (Yes, I'm completely and utterly serious.) I have to say, though, even if it was an awful plot with a terrible script and, of course, those wonderful special effects, it was very true to the spirit of Lost In Space. Just crazy, ridiculous fun. If anything, I got a good laugh out of Tybo, and the people-eating lettuce.
But still. As far as actually GOOD? No way. As far as fun? Definitely.
