I may be fourteen, but I am a true Christian. Therefore, the bloodshed and brutality do not matter to me, but rather the selfless act of sacrifice coming from Jesus himself. For the general audience (including non-Christians), I'd say the violence may be too much for someone else under 15. (But parents should know their children - if they're Christian and you know they can handle this, then in that case I recommend it for 13+.)
The portrayal of the people flogging, whipping, and crucifying Jesus may be graphic, but it proves that love is a powerful thing (esp. to us Christians) and sacrifice is sometimes crucial to save/help the ones we love (maybe not in this extreme form, though). When I watched this, I couldn't stop sobbing and choking up, it being so inspiring and sad and all (in a good way). But to be honest, I loved it and did not regret a single tear. The acting is simply superb. It even gave me a stronger heart and piece of mind. I will never have enough good words to describe this movie, with only a few bad ones. I have mentioned this before, but just to be sure, I'll say it again - this is not only excessively bloody but the crow pecking out the criminal's eyeball made me avert my eyes. There is a whole 10 minutes dedicated to the flogging of Jesus, which is not only an awful (though somewhat needed) sight but we hear his cries of pain, ripping of skin, his blood splattered around him. The whipping is more tolerable, but I don't think it is as long. Some soldiers press the crown of thorns into Jesus's head, which makes blood trinkle down his face also.
And the nailing... well, let's just leave it to that.
