I've already mentioned it in this thread somewhere (
edit - post 14
here if you really want my opinion), although I'm nowhere near any kind of 'authority', just someone with more than a passing interest on the subject.
Most people who saw this film just to see what all the hype was about seemed to come away learning something new, for example one guy I know used to think that 'Christ' was Jesus' surname.
VERY powerful film with only slight artistic licence used (the Bible doesn't mentioning satan being in the Garden of Gesthemane at the start of the film and I'm not sure why they added the part with the blackbird) and the timing of the film was perfect considering that Christianity and Christian values get constantly attacked today.
Very disturbing as well, many left the film in tears. It certainly made an impact on me. Throughout the film while they were beating Jesus I felt myself almost saying out aloud "leave him alone!!".
Perfect ending btw, can't wait for the sequel
