What just happened?

Well, I don't know why some articles said it's funny and cynical.. It's supposed to be funny as an 'adult black comedy'. I guess then, it has to be funny.. but I don't think it's funny... not even one moment.. I didn't laugh but I yawned... Only one reason I wanted to watch this film was Robert De Niro.. after watching this film, only one thing left in my mind is his performance... The image is from http://elysedmc.files.wordpress.com
