It's Really The American Way....
...to so be outrageous about nudity in this movie, and treat it like if it was showing porn. Not every American will feel this way obviously, but it's a common tendency nonetheless.
Not to speak of the offended women, unbelievable. You have got to be idiots, sorry, but you do. It isn't often a movie treats the female body with such appreciation and love like this one does, and you pound on it like if it's treating you like prostitutes or something.
The main character doesn't even look at any women at any given moment with lust or desire, he looks at them with always with fascination for their beauty and for the inspiration they gave him. When he sees Hustler as a boy, he even becomes nauseous for showing sexuality, other than the beauty he was seeking for.
Please mature yourselfs, and try to open your mind a little, because not everything in life is black, bad or devil when it comes to sexuality or the female body.
I don't think the movie is a masterpiece of any sorts, nor is it even one of my favorites, but it's a nice movie with some good ideas, and you are misinterpreting them.
Just one more thing, the Time Frieze isn't real, its beauty the main character as an artist sees the world. In the end, he can show it to his lover, with love (hence the kiss).
This is not a Sci-Fi movie, how did you ever got that idea?
