The movie wasted the talents of the actors in it. Jemaine Clement was really the only thoroughly funny character, and Steve Carrell was yet another oblivious idiot...other than that, the movie lagged in many places, really wasn't funny other than for a chuckle here and there, and generally disappointed overall.
Overall consensus from people leaving the theater as I did seemed to be "that wasn't nearly as funny as I thought it'd be."
