While "Forgetting Sarah Marshall" shares some DNA with "Knocked Up" or "40 Year Old Virgin," it is definitely a step child. What carried "Virgin" was the genius of Steve Carell and Catherine Keener. "Knocked Up" was watchable because of Katherine Heigl. Jason Segel is no Carell. He's not even a Seth Rogen. He's likable, but so is the guy who fixes my car. That doesn't mean I want to see a movie starring him.

This movie could have stood to be about an hour and a half shorter. If you want to see all of the jokes, just watch the preview. Only sit though the actual movie if you have a desire to see Jason Segel's schlong.

On a positive note, Liz Cackowski was the only thing in this movie worth watching, but she gets very little screen time.
