Incredible. Please give us an example that supports your claim.
I am not religious although I was brought up Protestant. I went in to the movie keeping an open mind as much as possible. I wanted to see if it 'made me believe'. I was also curious how someone who knows nothing of Christianity would view the movie.
From the non-Christian point of view, you have a guy, who believes that he is in some way divinity. In most cultures, that right there is a red flag. Numerous times, he shows utter disrespect for the Romans as well as the Jews. Rather than taking a diplomatic approach to things, he is very confrontational. I found it very hard to be sympathetic when it is obvious he is bringing most of the things that happen down on himself and is doing it willingly.
Again, I don't mean to insult anyone by saying these things, this is just the impression I got watching it. I highly doubt anyone from a non-Christian culture, who watches this movie is going to get much out of it besides Christians like to watch their 'God' being tortured to death.
