This is my favorite Scorsese film. I think it's more relevant now than it was when it was released. The relationship between fandom and obsession and danger is even more interesting in the age of gamergate and bat-fans.
These performances are fucking phenomenal. I love Jerry Lewis' performance, even though he really doesn't seem like he wants to be there. He exudes contempt and disgust, but I can't tell if it's his real-life apathy, or just a good performance? Anyways, he's great, De Niro is masterful, Sandra Bernhard has a fantastically funny, yet truly scary performance. It's so great.
ALSO, how Scorsese manages to put suspense into this weird dark comedy is so great. The scene of a paranoid Jerry Langford running down the street is one that creates an immense amount of anxiety for me. Absolutely lovely.
I'm all over the place, but this movie is so good. I wish Scorsese would do more comedy!
