A nice suburban couple realize they're in a rut and try to add a little zest to their life. Forced to 'steal' another couple's reservation at a popular restaurant, they are soon paying for that indiscretion and running for their lives (and repeatedly criticized for it by cop and criminal alike).
Carell and Fey do a believable job as a married couple who love each other, but need some time to keep their romance alive. The script gives them plenty of moments to discover what's right and wrong with their relationship and work through it in a relatively believable fashion, given all the mayhem.
Not all of the jokes work and not too many of them are outright hilarious. But this is a funny movie.
