Are nude women pointless and make women feel uncomfortable in movies? Unnecessary?
No one's particularly disturbed by nudity anywhere I've seen films. That includes the US and a number of other countries. I'm a woman. Nudity in films doesn't make me feel at all uncomfortable, and most of the time, there's a good plot reason for it. It's not "shocking". I've never been to a film with female nudity where the audience reacted as you describe. The people where you live must be very odd. You sound rather odd yourself.
Well here in the US we don't really have a problem with nudity in movies(which sounds weird to people, but the thing is we go in to the movies KNOWING it will be there, and that's different from people having a problem with it on broadcast TV to which i add notice people don't complain about it on HBO's Game of Thrones). So it's not about shock value and it's put in because people want to see it.
