I watched one episode. I found it pretty poor.
I don't mind that besides cannibalism, Hannibal bears nothing in common with the character we know and love from the movies. But the combination of no likable or interesting characters and tons of arbitrary slaughter with no emotional consequences bores the hell out of me.
I mean, why would this genius serial killer entrust his identity to some random unstable girl? Professional courtesy? None of the writing makes any god damned sense.
