I just saw it yesterday - and I'm surprised I didn't have nightmares about it last night. It's one of the most gruesome pictures I've ever seen, not for what Hannibal does, but for the reason given for why he does it. If you have kids, if you have a tender heart, keep away from it. I think I'm having post-traumatic stress disorder from watching it. If I could only get those scenes out of my mind!
I keep telling myself it's fiction, but it's too horrible to even be fiction.
And I say all this actually having enjoyed the other Hannibal movies (though Hannibal was boring), and having loved Silence of the Lambs. I love horror movies in general - but there are limits and this movie crossed them.
