I'm not being all like "we need more naked parts all over the place", just that the double standard is really weird to me. Violence is pretty gross (though conflict being a part of drama it does sometimes need to be there, just not all Eli-Roth-style where someone is lovingly grinding someone's face into, like, a face grinder for twenty minutes), sex (or even just the wrong body parts being visible) is icky to the weird puritan mindset that still hovers over America generally, so we err on the side of SUPER COOL GUN BATTLES.
I had a roommate that liked to watch movies while he worked at home. I would joke (because he would watch them REALLY LOUD and it was a small place) that it sounded like these movies consisted nearly entirely of screeching tires, broken glass, and gunshots. I'm sure there was a lot more going on, but all those being kind of high-frequency sounds it's all I would hear through our doors. But those three sounds happened REALLY OFTEN, and slowly I realized through my irritation that I didn't have a ton of interest in movies that centered around those things.
Not sure what my point is here. Anyway.
I remember distinctly that in season 1 of Hannibal there was a scene with flayed corpses. The standards & practices team told them that they couldn't be shown... because their butts were were visible. So they covered the cracks with more blood. Good to go.
