These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Award Snub: Keitel's performance is one of the best ever put on film and didn't even get an Oscar nomination.
Narm: Any of the sex scenes, except for the Nun's.
He Really Can Act: After seeing him here, you will be genuinely baffled as to why Keitel has never won an Academy Award.
Not that anyone ever really doubted his talent before, but this was his first time in a lead role, and proved that he could handle a film on his own.
Jerkass Woobie: The Lieutenant. At first glance, he's an absolutely despicable individual with no redeeming features. Then we see the depths of his self-hatred and despair and just how desperately he wishes he could be a good person but feels that God has completely abandoned him.
Moral Event Horizon: The Lieutenant appears to have crossed his long before the movie starts. In the movie itself, he pulls over a couple of teenage girls and forces them to expose themselves and act out various sexual activities while he masturbates, and ogles a nun who is being medically examined following being gang-raped amongst others, however.
That said, he is not a sociopath, he commits his acts not out of pleasure but because he doesn't know how else to act. He is full of deep self-loathing and remorse for what he has done and believes he is beyond any levels of redemption.
Tear Jerker: The Lieutenant's breakdown in the church. The character is ripped apart and shown as a human being desperately trying to find some sort of hope for redemption and who feels completely abandoned by any sort of deity.
True Art Is Angsty: Have no illusions. This is a crushingly bleak and unhappy affair from beginning to end. And it is absolutely brilliant for it.
