I totally disagree with that critics assessment of what its about. First let me say that I watched this at the local theater. It was a sell out. The youngest person in the theater was fifty years old.
The movie is graphic yes, it shows what we did to Christ. When I say we I mean all of us. I did not hear one single person place blame on the Jews or anyone else in particular. I did see a group of several hundred people who were so affected by the movie that they sat there and didn't get up. No one was telling jokes or poking fun. Some were praying, most were crying. I too grew up with the old movies of the cleaned up version of what Christ went through. But it in no way conveyed the actual horror of what took place. Like you, I have a much longer version of what took place and it does much better explaining the movie and the introspection that comes from it. Its not a fun movie, I didn't enjoy it. I couldn't watch it over and over again. It did cause me to think about my place in things and have I led a life that was what it should have been. The movie is not demeaning, it tells a true story of a true event. If this event were played out today would the outcome be any different? I don't think so. Remember a blind eye was turned during WWII and the extermination of millions. Even now you don't hear an outcry over the million people that Iraq eradicated over the past ten years.
The movie depicts a violent graphic hideous time in our worlds history. Should we sweeten it up so it doesn't offend. No. Do we gloss over Buchenwald, Auschwitz, Treblinka or Iraq. No we show what happened and mans inhumanity to man in hopes that we will change and make this world a better place to live.
My suggestion is that if anyone doubts the movie watch it for yourself. Don't let someone else fill your head with a bunch of stuff with no proof. It will cost you a couple of dollars and two hours and twenty minutes of your time.
