Just watched it. Very interesting, atmospheric, and kind of creepy movie. It's one of those slow moving kind of "artsy" movies. It's a bit vague. Had no idea it was based off a novel. Great soundtrack. I'm curious about some things though. [spoiler]My take is that the motorcycle guy was also an alien. I think they were maybe feeding/creating another alien? I say that because it showed that one scene after one of the victims where there was what looked like an alien body possibly forming.[/spoiler]
