This is a terrible unfunny comedy
The only reason I purchased GALAXINA on dvd years ago was because of the late Dorothy Stratten. This was supposed to be a science fiction comedy satire, obviously spoofing Star Wars and Star Trek and others, but it just doesn't work.
I actually don't want to blame the movie's actors. The whole story line is bad. These actors did what they could with the script. They probably needed the paying work as well. Dorothy Stratten was just breaking into the Hollywood movie business so she was in no position at this time to be choosy with roles. Had she lived, she would have gone on to garner greater Hollywood success.
I didn't laugh once during the movie. Well, maybe I did find some humour at the asteroid bordello scene where it looks like aliens from Mos Eisley Spaceport of the desert planet Tatooine were hanging out. There were some moments there, like when the space captain put a brown paper bag over an alien hooker who had a terrific body but a prune face.
Still, I would only recommend purchasing GALAXINA if you are a Dorothy Stratten fan and you want to feel sad watching her during this movie.
