I'm taking this one in doses. I'll probably finish watching it tonight. So far, what has happened in this movie (the special R-rated version) is that these people are on a big space ambulance when they receive a distress signal from some far-off planet. They all have to get naked to make the hyperspace jump (or whatever they call it in that universe), and the only reason I could see for this is so that we could all see Robin Tunney's boobs. (I think that's her name.) Anyway, we learn that she and Riche Valens are an item, which means they have a long-term sexual relationship. They want a baby, and she seems obsessed with having sex. She later does it with the bad guy. Anyway, they get to the planet and kill time Boob lady does it with Richie Valens, while Tina Turner does it with the captain. The other crew member (a Geordi LaForge ripoff) plays chess with the HAL-like computer. Eventually, the bad guy comes aboard and he has a wierd glowing orifice with him. The bad guy is bad because he wants to keep his orifice, and tries to kill the captain when the captain tries to get rid of it. It turns out the orifice is a bomb. The orifice seems to give the bad guy special powers too. First, he bangs Robin Tunney. Than she pretty much disappears (assumed dead.) Bad guy kills Richie Valens and Geordi too. He also smashes all but one of dimension jump pods. Well, the captain gets back, and he and Tina Turner shoot bad guy and the orifice off into space, and they explode. The two good guys get to the pod just in time. The star went supernova. Since they had to share a pod, their DNA mixed a little (meaning that he got one of her eyes, and she got one of his.)
This is a truly awful movie and the perfect example for what's wrong with filmmaking these days. It could have been good, but the studio decided to make it like this instead. It's a lame excuse for special effects.
