Oh, ABC. How adorable that you felt that your sad new sitcom Man Up! (8:30/7:30c) deserves an exclamation point. As in, maybe: Yikes, this sucks! The network describes this latest "comedy" about male insecurities as being "in the vein of The Hangover." Only in the vein of people who watch The Hangover and think: Boy, I wish I could be that funny.
