The cover art suggests Aliens, but it's more of a DOOM scenario, with creatures that would fit in that movie instead of ALEINS, and DOOM clones haven't been done to death either. I don't know why people gripe about seeing yet another "take" on a familiar theme like ravenous creatures on board a ship. If one counts the number of vampire and werewolf movies that come out every year, then we really do have something to talk about. I looked forward to seeing this film and was not disappointed. It took little time to get right to that action, and those slimey humanoid creatures are really great too look at. And for once, you didn't have to wait for half the movie to see them. They are in your face right off the bat, and the camera gives you lots of great looks at them rather than shots so brief that you have to pause your player.
This movie is a hard one to seek out, as I wasn't even aware of it until I saw the title in an "also available" section on the dvd special sections of DEMME KING, THE SEA MONSTER. Thanks to Blockbuster for having it available to rent and to Amazon for having lots of good prices to buy.
