I was really enjoying Art School Confidential (2006) a lot -- perhaps something you have to really *get* to understand, seeing into the main character's head, yet still seeing beyond it -- but then there's the last act, when everything just fell apart as far as I'm concerned. A shame, really.
A talented young man goes away to Art School and falls in love with a model. Technically, he's perhaps the best artist around, but the "fake" artist gets the girl because this young man is missing something -- and his mentor provides the catalyst he needs. Now... also add a serial killer to the story to kick it up a notch. lol
