The plot and story line isn't all that deep. I mean, basically they get chased around all night. What makes this comedy work, is the actors. Tina Fey is funny as ever. She always makes situations funny, even if they normally wouldn't be. Steve Carrell is the same way. They MAKE this movie. If you liked Baby Mama, or if you like The Office or 30 Rock, you'll like this movie. Trust me, as soon as you hear Tina yell "I don't want the kids to live with your mother....she's awful!!", you won't stop laughing.
