Don't let the fact that this is set in a space station orbiting a star about to go nova fool you. This is a low tech story. Their ship is huge, but for no apparent purpose other than to provide a lot of corridors in which to play cat and mouse. The conflicts are solved with 1980's vintage firearms and in some cases a knife.
This movie bounces between some great parts and many that make absolutely no sense whatsover. I like the characters; the actors are excellent at making them work. But what kind of mom thinks its the right thing to do for a 16 year old daughter to get over her fathers death is to spend nearly two years in an isolated space station? No contact with anyone but her mom and stepdad-to-be. By the time a guy shows up the poor kid is so horny that she damn near mounts him even before he comes out of cryo-stasis! (This happens on her 18th birthday, which mom forgot about.)
The inevitable fight sequences is where the movie works best. Enjoy it for that and forget the rest.
