I don't generally endorse any dramatizations of the Life of Christ. They are usually not called for. But I think the Mel Gibson movie was over-promoted and rejoices too much in the sufferings of Christ. It is too hard to watch. We shouldn't be glad of what happened to Christ. I'm sure that was not the intent of the film, but the film is too sensationalistic. ISTM, the best version of the Gospels on films is the 1977 film by Sir Lew Grade in England, Jesus of Nazareth. Other than the fact the Robert Powell has blue eyes, and that wouldn't probably be like Jesus, the film is fairly watchable, and the part with Powell and Ernest Borgnine as the godly Roman Centurion is very memorable. Also, the part where Powell plays the Lord when He has risen from the dead, is good for a film to show. Take care.
This is just my opinion, and I could be wrong to believe any depiction of the life of Christ on film is permissible. As long as it doesn't become an idol, the idea isn't ISTM automatically suspect or forbidden.
