Andrew Sullivan’s review of the film may be almost as brutal as the film itself.
..the movie was to me deeply disturbing. In a word, it is pornography. By pornography, I mean the reduction of all human thought and feeling and personhood to mere flesh. The center-piece of the movie is an absolutely disgusting and despicable piece of sadism that has no real basis in any of the Gospels. It shows a man being flayed alive – slowly, methodically and with increasing savagery…. No human being could survive it. Yet for Gibson, it is the h’ors d’oeuvre for his porn movie. The whole movie is some kind of sick combination of the theology of Opus Dei and the film-making of Quentin Tarantino. There is nothing in the Gospels that indicates this level of extreme, endless savagery and there is no theological reason for it. It doesn’t even evoke emotion in the audience. It is designed to prompt the crudest human pity and emotional blackmail – which it obviously does.
On the subject of whether the film is anti-Semitic, he has this to say:
Is it anti-Semitic? The question has to be placed in the context of the Gospels and it is hard to reproduce the story without risking such inferences. But in my view, Gibson goes much further than what might be forgivable. The first scene in which Caiphas appears has him relaying to Judas how much money he has agreed to hand over in return for Jesus. The Jew – fussing over money again! There are a few actors in those scenes who look like classic hook-nosed Jews of Nazi imagery, hissing and plotting and fulminating against the Christ. For good measure, Gibson has the Jewish priestly elite beat Jesus up as well, before they hand him over to the Romans; and he has Jesus telling Pilate that he is not responsible – the Jewish elite is. Pilate and his wife are portrayed as saints forced by politics and the Jewish elders to kill a man they know is innocent. Again, this reflects part of the Gospels, but Gibson goes further. He presents Pilate’s wife as actually finding Mary, providing towels to wipe up Jesus’ blood, arguing for Jesus’ release. Yes, the Roman torturers are obviously evil; yes, a few Jews dissent; and, of course, all the disciples are Jewish. I wouldn’t say that this movie is motivated by anti-Semitism. It’s motivated by psychotic sadism. But Gibson does nothing to mitigate the dangerous anti-Semitic elements of the story and goes some way toward exaggerating and highlighting them. To my mind, that is categorically unforgivable. Anti-Semitism is the original sin of Christianity. Far from expiating it, this movie clearly enjoys taunting those Catholics as well as Jews who are determined to confront that legacy. In that sense alone, it is a deeply immoral work of art.
In contrast, Roger L. Simon answers this question in one sentence.
Finally, was it anti-Semitic? Of course, but what do you expect from a film that treats the whole subject so brainlessly?
