Tina Fey and Amy Poehler in Baby MamaBABY MAMA

Despite its sunny, friendly veneer, there's a rather scrappy little war being waged within writer/director Michael McCullers' Baby Mama - one between a lighthearted, pleasant sitcom and a sharper, smarter, more cynical sitcom. (Two and a Half Men versus 30 Rock, as it were.) The former wins, and we could have predicted as much, but the best parts of this engaging buddy flick suggest the truly sparkling comedy it might have been, if only it weren't so eager to be ... well, lighthearted and pleasant.

Dennis Quaid and Sarah Jessica Parker in Smart PeopleSMART PEOPLE

This past Friday, a couple of friends and I were discussing the long-delayed return of new episodes of NBC's Thursday-night comedies - the unfailingly hysterical 30 Rock and The Office, the shrill, irritating My Name Is Earl, and Scrubs, a show I've occasionally endured when I was feeling too lazy to change the channel. One of my friends admitted that Scrubs has been off its game for quite a while, but said he sticks with it because, after seven seasons, he's become too invested in the actors and their characters to stop watching. I felt the same way during director Noam Murro's Smart People.
