Damn got here a bit late. As Scott said The Passion sucks ass. It's just a mindless Hollywood action movie.
I haven't seen any of the other ones except the great Last Temptation and I'll go along Muzic trail here. The greatest thing about the movie is that it shows the human side of Christ: suffering from fear, rage, temptation and heck, he wasn't even sure it was God talking to him, but he overcame everything and became the great person we all know from the gospel. As a movie it has great photography, sountrack (Peter Gabriel), scenery and it has the great David Bowie. One of my all-time favorite movies. I give it two thumbs up and 5/5 stars
