In the 1960s and 70s he was quite funny. And occasinally in the 80s.
He was OK for a while, he ran into problems when he started believing his own press. Mel Brooks has a similar problem. Woody’s problem has been made worse by the fact that he’s deeply neurotic and seems to have a hard time finding anything to write about other than his severe emotional problems. The only good thing he’s done lately is put Scarlett Johansson in a lot of movies, not that she’s any good, but she’s hot, I think he thinks by putting the biggest boobs in Hollywood in his movies we’ll forget about his under age girl issues.
