Space Mutiny is so bumbling and terrible that one would be hard-pressed not to fall asleep on it, and I did the first time I saw it. Not even the presence of John Phillip Law could save this piece of 1980's sci-fi garbage. Thankfully, the crew of Mystery Science Theater 3000 makes it memorable, and nothing else. It has all the appeal of a dingy and smelly mattress floating on a pile of sewage, and even then that's giving it too much credit. It's only entertainment value is its unintentional comedy, but you have to be really dedicated to get through it as it's spotty and doesn't come all at once. If you're going to see this, I recommend seeing the MST3K version only. That's about the only way one can sit through it.
