"Don Jon" rather successfully shows, even in just its opening montage, how firmly sexuality is placed in our society, and the endless spotlight on it that never seems to dull. However, the ceaseless nudity and hookups can be a distractor, and can cloud Gordon-Levitt's message at times. But he gives a fine performance as Jon, nailing the accent. Jon's a porn addict, and his girlfriend is an addict herself: a lover of romantic comedies. What's the difference between them? On the surface there's a big ordeal, but JGL makes you think where the lines are blurred. This movie, like actual pornography, is absolutely 18 years and up. I can't even see this being broadcast on basic cable it's so filthy.
