I'm impressed by his work ethic (the man has released a lot of movies) but I only like a few of his movies. I kind of feel the same way about him as I do Chris Brown or Justin Bieber. I like some of their songs, but I don't have a lot of respect for them as people.
Anyway, I did like "Midnight in Paris", "Annie Hall", and his latest release from last year, "Wonder Wheel". A lot of his movies are formulaic though...and they always seem to focus on weird romances or strange 'inside-joke' type plots that I don't really understand.
Oh well, no movie is made to please everyone.
