Frankly, I don't think this movie is as bad as some people make it out to be. I like the early episodes of the original series (particulary the first six), when the show had a more serious tone (and before Jonathan Harris sabotaged it by turning up the comic antics as Dr. Smith) and it's nice to see the film stay closer to that serious tone and not emulate the more campy aspects of the series from its later episodes. The cast is good for the most part and I love the visual FX.
However, once the Jupiter 2 crashes on the planet and we get caught up in the time travel older Will Robinson bit, that's when the movie falls apart completely. And the biggest mistake of all is that the older Will Robinson is not played by original Will Robinson, Bill Mumy, even though he badly wanted to play the part. Having listened to the comments of the director on why he didn't cast Mumy on the DVD, I have to say his explanation doesn't wash. Especially when both he and the scriptwriter concede that the device of using the "older Will Robinson" didn't work on the screen as it did in writing. It never occurs to them that maybe the scene would have worked if this new character sprung on us was someone with a definable connection to the old show.
