Gosh, I haven't watched the anime yet. >__>
I am soooooooo behind time these days. I've read the manga though, and I love the art, and the story. It definitely is different from anything I've ever read before. Scary, though, if something like the Death Note were to actually exist in reality. *shudder* Yeah, I don't see why you shouldn't get the manga. I usually prefer the original manga to the animated versions anyway - but only because a lot of anime are condensed versions of the manga.
