I asked about a plot point, which you confirmed was true. Having someone sent to jail for a crime they didn't commit is the sort of miscarriage of justice which good movies generally seek to unwind (a la Shawshank Redemption) rather than affirm. The fact that this movie doesn't do that, kind of takes it off my must see list.
So...
The Passion of the Christ is a bad movie?
Innocent man being put to death and all...
That one won't give a straight answer, so I'll fill in with the honest response: it is worse than that. The "detective" not only allows an innocent man to go to jail by suppressing evidence that would've exonerated him for politically correct reasons, he also takes a bribe, of sorts. The superior who pressures him to do this holds out the promise that the detective's brother, who'd been in trouble with the law, will have his record cleared if he goes along.
And this is done. Just gets better and better, doesn't it?
I think the movie was trying to demonstrate that those kinds of injustices happen in real life, and if they resolved it in the movie and justice was served, then the filmmakers would undermine their own point. The movie is realistic, instead of being a cheezy feel good movie.
