I was worried this would be a movie for 20-somethings, based on the title. But the characters are all different ages, and it's a really unusual bunch of relationships / dynamics. The young guy in the movie isn't so obnoxiously precocious and talented that you want to puke because your life is a giant joke compared to his, so that was also a relief. (I honestly can't bear to watch another movie where a 23 year old is more creatively fulfilled and confident than I am in my 40s, and has a nicer apartment and is having more sex, to boot. Srsly, really, Hollywood, are you TRYING to make me want to kill myself?) ANYWAY. This movie wasn't like that. It was charming and weirdly relatable despite being incredibly unlikely ever to happen to me or anyone I know. Plus, SUCH A GREAT CAST!!!!
