I found this a very bad movie.
Regardless whether you believe the crucifixion-story of Jesus (which I don’t), there are no interesting insights offered. We only see suffering to an inhuman extent. If you’re not a believer, it comes across as silly and cruel and I can also imagine that as a believer you question the ‘message’ of this movie.

Supposed I believe in the story of Jesus as told by the bible, then what message do I have to see? We know the story of his suffering, but that was just illustrative. Isn’t it about the message behind it? Why did he suffer that much? How could he take the torture? What was the result of it? What did it to him as a (hu)man? Did he never lose his faith and why?
To me all these questions are much more interesting than watching gorey torture-scenes for hours at an end of Mr. Mel ‘I-like-to-have-a-torture-scene-in-every-movie-I’m-in” Gibson.

As a non-believer you don’t get an insight or understanding either. However, you could explain it to atheïsts by showing the human side of the story or the historical context.
I DO agree that the Jews were painted in a black-and-white manner. If you believe in the bible story, you’ll know things were a bit more complicated than that. If you know more about the history, you’ll even know that the whole story is one of enormous complexity.

As far as the acting goes: non-present.
Caviezel only takes the beating of his life and the two women have no dialogue and only look distraught and cry. That is it.
The original languages spoken I did find interesting, as an amateur linguist.

Gibson could better make another Lethal Weapon than another bible movie.

(for the historical setting only)

Usually I shun movies which are being hyped so much, because it then becomes difficult to see it as is.

What most people forget is that the explicit torture scenes are a real trademark of Mel Gibson: in almost every movie he has explicit scenes where his is lengthily tortured (Braveheart, Payback, Lethal Weapon-series, Conspiracy Theory, etc). The guy’s just a freako!
