LOST IN SPACE--Based very loosely on the popular classic 1960s television series about "The Space Family Robinsons" who leave a depleted and overpopulated Earth for the Alpha Centauri star system to colonize a habitable planet. About the only saving quality of the movie is Mimi Rogers poured into a skin tight jumpsuit. The B-9 robot, perhaps the most expensive SFX in the film, only bears a remote resemblance to the original robot--also featured in a Taco Bell commercial.
Looking at the original series, the SPX were pretty cheesy and science had little to do with anything. Examples: Space aliens on a ship which captures the Jupiter 2 are just golf carts covered in cheese cloth equipped with cattle prods. During a spacewalk, a comet passes by. Heat from the comet causes the access door of the spaceship to jam. Irwin Allen, which produced the series, was the king of Sci-fi TV back in the 1960s--with such shows as Voyage To The Bottom of The Sea, The Time Tunnel, and Land of The Giants.
