A pretty weak plot supported by fairly good SFX. The driving force for the movie is that hybrid human-alien people are suffering from a disease that takes away the human part and turns them into mindless human killing things. There's a quest with a strict time limit to a place no one has ever been to retrieve a magic space egg. There's an unsurprising twist. There's a lot of hacking at rubber and plastic costumes. The actors make a good go of it, but it can't be easy given the script: "I'm good. Hahaha, no, I'm evil, but I've got an excuse."
