DO NOT READ FURTHER UNLESS YOU ARE NOT GOING TO SEE THE MOVIE - SPOILER ALERT!!
My favorite part is after the artist has "passed on" he visits his dad in a dream. There is a running theme throughout the film that Deniro tells David (the artist) when he's a little boy that he shouldn't paint walls because dogs pee on walls. He should be an artist. It turns out that David has kept this with him even as he's grown up, and has even told the gallery curator those exact words and that he wouldn't be an artist if it weren't for his dad. Maybe because of the pressure, David succumbs to drug addiction, and towards the end Davids child self in Deniro's dream sequence tells Deniro that maybe next time he'll just have a regular job like a painter. At this point I was balling all over Martin's shoulder:) You can just see a father's guilt for pushing his son too hard here. Deniro is a genius in this film and the storyline is all too realistic in todays world. Great tearjerker if you're in the mood for a good cry!!
