This is not a film for the feint of heart, the light of mind, or the easily queasy. This film is as grotesque as the trailer(s) depict.
It's an amalgamation of lots of depraved symbolism and concepts of idolatry combined into a loosely connected story about an assassin (though, I would probably think of him more as a mercenary) attempting to carry out a relatively righteous mission (heavy emphasis on "relatively").
It's a disheartening, disgusting film, to say the least. More-so because of the way it depicts what a living hell would be like in the worst ways imaginable.
The film takes no short cuts in dissecting and outlining what the worst possible outcome could be for those unfortunate enough to be trapped in said hellscape, and it's every bit as horrifying as your imagination may (or may not) be able to conjure up.
It's also a hard film to rate -- amidst the mortifying displays of disturbing viscera, there's an obvious tale here, if not a blatant warning message in some sense.
Though I get the impression that the people who should be watching a film like this to get the wake up call, aren't going to be the people who are drawn to this film, so it's likely only going to be preaching to the choir.
Even still, it's a tour de force in stop-motion animation. There isn't another stop-motion project out there that really compares in terms of depth and scope. I wasn't the biggest fan of the minor live-action integration in some segments, but for the most part it all worked quite well.
But don't go into this thinking there are rainbows and lily-pads about. A fair bit of warning: all ye who enter, abandon all hope.
