*SPOILERS* that weren't the creatures getting ripped apart was the whole escape pod scene (reminded me of System Shock 2) and the protagonist getting sucked into space.
Other than the action scenes, I pretty much forgot about everyone in the movie five minutes after it ended.
If you like Dead Space like I do, what the hell, give it a whirl. It'll be airing on Encore Action again this Wednesday, at 11PM Pacific. It's entertaining, but don't expect any John Carpenter masterpiece.
