Sour Grapes is a comedy about things that aren't funny. It reminded me of Crash, an erotic thriller about things no one finds erotic. The big difference is that David Cronenberg, who made Crash, knew that people were not turned on by auto accidents. Larry David, who wrote and directed Sour Grapes, apparently thinks people are amused by cancer, accidental castration, racial stereotypes and bitter family feuds... The more I think of it, the more Sour Grapes really does resemble Crash (except that Crash was not a bad film). Both movies are like watching automobile accidents. Only one was intended to be.
