Yes, it was graphic and maybe it wasn't really necessary to show the violence to that extent. I did look away during some scenes. However, torture and being crucified is violent. I don't think it was a particularly good film anyway. It's just a vivid depiction of the death of Christ.
"I think the argument that anything is ok if it opens up discussions is pretty weak to be honest. "
I'm not saying that "anything is ok" nor am I excusing the use of graphic violence either but I don't agree that it was glorifying violence either.
There are loads of other films that use violence for the sake of using violence yet are enjoyed by the general public, no one bats an eyelid at that. Yet when showing the suffering of Christ, you get contraversy that it's too disturbing!
Are you Christian btw?
