Black Swan had a bit of that as well. Me and the wife were watching it together and it was mildly uncomfortable, but the movie was interesting enough otherwise to carry through. Apparently if you can pull off lesbian porn in a classy, artistic way, that debatably adds to the story, that lands an actress an oscar.
Speaking off lesbian actresses, I watched Birdman. 3/10 Fail.
My advice? Don't. Just a boo-hoo, woe is me film about a declining hollywood action actor (Micheal Keaton) trying to make it in Broadway. I hate self-serving hollywood/broadway movies that just cry about how hard their puff, artsy lives are. But I get that others may like it, in particular those in hollywood or broadway. This movie won some awards, but I felt the overblown performances and the sillyass depressing story weren't quite good enough to justify that. But when movies are made to glorify or pity the industry, chances are that industry will hand out a trophy and some kleenex.
Black Swan, a similar type of movie, but lacking the pathetic nature of Keaton's crybaby character and ho-hum plight, is superior in every way.
