Not the best example of 50's science fiction or horror, but a good 80 minute or less time waste. Astronaut brings back an alien presence that wants to take us over. What else is new, right? Not much here that is new, but it was nice to see the goofy looking blood beast running around causing mayhem. Reminded me of an ugly, retarded gorilla. Run for your lives. Not the best place to start if you wanna check out 50's sci-fi, but it's campyness may grow on ya.
