I'm not asking if you think such things should be banned or whatever, blah blah blah, just if there is any such things you've seen that seriously disturbed you and you were possibly worried children could access it.
Answer: No. I found the smoking in Sin City far more offensive than the violence.
Well, putting aside the smoking and the violence and the bad language and whatnot, I find the fact that
Sin City is a plotless, overhyped piece of trash which was hailed as "original" by a bunch of tools who have clearly never seen
Casshern to be what was truly offensive about this movie. Not that I'm unhinged or have a disproportionately strong way of expressing my opinion or anything.
On the more general question, I have never been offended by a movie on grounds of violence. I don't particularly
like gory movies if the gore is there solely for kicks and doesn't carry some kind of underlying moral message, but then again I don't have to watch it.
