The Hangover Part III perhaps stays most true to its namesake considering just how forgettable it is.

What happens in Cedar Rapids, stays in Cedar Rapids. That spin on the traditional Las Vegas slogan is voiced in Miguel Arteta’s latest — and given the presence of Ed Helms in the lead rol, and a plot that involves crazy things happening in a city that’s not the home of the gang of lead characters, it might be easy to assume that this is simply a midwestern spin on The Hangover. But that incongruous line, which equates the bustling not-quite-metropolis of Iowa with Sin City, is actually delivered in a poignant moment, and not to play on the laughs inherent in that disconnect. It’s an example of the ways in which Cedar Rapids really isn’t much like The Hangover: it never gets so out of hand in pursuit of crazy comedy that it forgets the basic humanity of its characters.
