I know this sounds daft but I don't mind a good thriller, mystery, sci-fi etc that contains violence that relevant to the story and dealt with in one scene. I'm a huge Sopranos fan and you can't watch that without wincing a few times!
It's the over-graphic scenes they feel we need to keep seeing again and again throughout that I don't like, especially involving torture, state of bodies etc. I don't watch the news as much these days for the same reasons - or read newspapers. I don't want to be "entertained" to an extreme extent with what happens in the real world to people and animals.
This penguin series has been a real treat.
Sorry if this doesn't make sense, I know what I mean lol!
