I'm addicted to it as well, if for no other reason than curiosity as to what that damn monster is (or if it even exists at all :p). Things just keep getting weirder every week, and it doesn't seem as if anything's been really explained yet; it's great storytelling. Plus, there's a hobbit on the show. :)
Does anyone else suspect that Boone might not be dead after all? With all of the crazy stuff that's happened so far, it almost wouldn't surprise me if he came back to life. I'm waiting until he's six feet under to make the call, and even then I'll probably have some lingering suspicions. :P
