"Galactic Odyssey" - the American title of Starquest II - was a horrible movie. The plot was amazingly bad, and the writing was some of the worst that I've ever seen. The overall premise - a group of humans, kidnapped to start a breeding program on another planet - seems fairly standard. That's when everything starts to break down.
First, the movie is interspersed with a lot of war footage from different places on the planet. None of it has anything to do with the people in the movie. There's a long montage at the beginning of various science fiction stories; none of it has anything to do with the plot of the movie.
Second, the effects and sets are bad. I mean, "Manos, Hands of Fate" bad. The airlock that closes off to prevent the ship from decompressing? You can see the lights on the other side of the door because the door doesn't close all of the way. The "robot" pilot that gets blown out of the broken bridge window because of decompression? He takes a nice stroll over when he's "caught" by the decompression. Just horrible. The "alien" hands on the actors seemed to have been bought from the props department of another movie - another cheap, badly made movie.
Third, the soft-core porn sex throughout this movie was a little bit of overkill. Kate Rodger, Gretchen Palmer and Jolie Jackunas are all hot, no doubt; but, did they really have to have sex every ten minutes throughout the movie? The women that I know would not respond to a "kidnapped at the last second before earth was destroyed" situation by doing it as much as they did. From an entertainment standpoint, this made the movie watchable; from a plot standpoint, it was ludicrous.
Fourth, the plot. Were the humans kidnapped because earth was destroyed, or because it was going to be destroyed? Were they breeding to be "harvested," or breeding to save the human race? Nothing was remotely clear; worse, nothing was remotely consistent. THe story changed as the movie went on.
Eh. There's better porn on the internet. Watch Mystery Science Theater instead.
