THIS is a movie for people who tolerate, even enjoy, plots with low-range credibility, delivered with unrestrained profanity, vulgarity and stupidity.

In Glenview Iowa, after the violent death of the nightwatchman, Costco manager Evan (Ben Stiller) calls for volunteers to form a neighbourhood watch group to catch the killer.

Bob (Vince Vaughn), Franklin (Jonah Hill) and Jamarcus (Richard Ayaoade) are the only takers. Each has his reason, not really connected to neighbourhood-watch principles.

The film is written by a trio including Seth Rogen, whose place in the pantheon of the stupid American comedy genre is front and centre, this time wandering beyond his usual comfort zone by bringing in an alien invasion about to take over the world from that small, mid-western town. The advance guard is already in place, masquerading as people.

Rosemary DeWitt plays Evan’s wife, desperate to start a family, unable to understand what’s the delay. And the denouement, in the truest tradition of problem solving, involves a lot of gunfire and a big explosion.

Been there, done that. Yawn.
