Well, here's what I think...
It's directed by Mel Gibson, very pretentious (more so than The Passion of Christ, I reckon) and up it's own bum. It's needlessly violent and gory (though not scary) and it's very difficult to follow with subtitles. Not a fan. But then I hated Braveheart and a lot of people liked ('Freeeeedddooommmm!' Shut up Mel Gibson and don't you ever flash your hairy arse at me again!) it, so take what I say with a pinch of salt.
