Rawson Marshall Thurber

Gleefully silly...plays like an extension of a Ben Stiller Show sketch (but a pretty good one, at that).

Mean-spirited to squishy does not a convincing trajectory make...That wouldn't be so much of an issue if We're the Millers weren't such a dismally unfunny endurance test, but there you are.

Even if the material's not always up to the title's ironic reference to wit, the cast and their director carry the day with a good stock of laughs.
