The season finale is well worth the watch. It is a really, really gory show, though, and more than a few episodes gave me nightmares. If gore and violence get under your skin easily, I'd say avoid it. It's definitely gorier than Dexter. It took me about five episodes to really get hooked on Hannibal, and with Dexter, about six. The first and fourth seasons of Dexter are really, really solid. Definitely recommend that one as well.
