TINA Fey and Amy Poehler’s comedy about two sisters throwing a house party feels like an overextended Saturday Night Live skit. It was funny at first to see Fey and Poehler play sisters who are polar opposites of each other. The irresponsible one teaches the other one how to let loose and start enjoying life. The smarter one teaches the other how to start living life responsibly. Then it stops being funny simply because the jokes become predictable and tiresome. Watch this only if you really like the comedic pairing of Fey- Poehler and can forgive them for the travesty that is Baby Mama.
