It's a bit of a mixed bag
I liked this movie but it was difficult. That’s because Robert De Niro doesn’t play a good person. He’s a comedian and TV star on the downside of his career and he’s angry about that. For most of the movie he’s a bitter and grumpy old man. On the positive side there’s his stand up. That also includes a lot of guest appearances by real comedians. That was funny. In fact the ending his completely hilarious. There was also a love story thrown in with Leslie Mann which I thought was up and down. That’s how I felt about The Comedian overall. It’s a very mixed bag.
