Query: Pretty bad

I love Ben Stiller, especially his earlier comedies (e.g. Duplex, Envy, Along Came Polly, etc.) but this movie is really bad. Unimaginative, cliche script, unintelligent dialog, weak + contrived plot, lots of foul language and worst of all ... very little that was funny. Back off from this one. Way off!
