Amen, I have seen the movie and one very important scene is Jesus saying how He is laying down His life, no one is taking it.
He does it because of His Perfect Love for us and His perfect obedience to the Father
The violence is necessary to show the magnitude of both
No one seems to mention the Resurrection at the end.
It was shown in a way never seen on film, brief but amazing joyful
Also I am Italian and I am not offended by the depiction of the Roman guards.
Rome was very brutal in its treatment of prisoners.
In addition, Christ's suffering joins Him to the suffering of all humanity...throughout the ages humans have died in degrading, humiliating ways from all causes, natural and murderous...the suffering of Christ means that He can say, to anyone, "I share your pain." We have a Savior, not only on a sunny day, but in the agony of our own end, whatever it may be.
