2006's "RV" by way of 2008's "Pineapple Express," "We're the Millers" is a proudly rude, unashamedly vulgar road-cum-drug comedy until it turns all gooey in the home stretch. Episodic but very funny much of the time, the film has been directed by Rawson Marshall Thurber (2004's "Dodgeball: A True Underdog Story") with a good-times flair, while the bevy of screenwriters—Bob Fisher & Steve Faber (2005's "Wedding Crashers") and Sean Anders & John Morris (2010's "Hot Tub Time Machine")—turn to a cavalcade of middle fingers and four-letter words when all else fails. The cast throw themselves into their parts and look to be having a wild time, a feeling that rubs off on the viewer until the story's soft, emotional side takes over. The problem isn't that it fails to be "heart-warming," but that said emotions seem disingenuous coming from these particular rough-edged characters.
