As I understand it, there are a few things here and there that could be viewed as anti-semitic. Caiphais is portrayed as bloodthirsty and never has the qualms that are in the Gospels. Pilate is portrayed as namby-pamby, which is probably in keeping with the Bible, but not history. There are apparently scenes where the Jews try Jesus that aren't in the Gospel. And so on.

It doesn't help that Gibson's father is a raging anti-semite.

But, regardless, it's important to point out that Jesus and his followers were Jews, so if all Jews are responsible, so were they. And, more importantly, if Jesus hadn't died, Christianity wouldn't exist.

That being said, I think it was well construed somewhere that for those who are anti-semitic anyway, there's going to be fuel. But for those not, it's just a story, regardless of its importance.
