The Watch is a silly movie. If you like the delirious antics of Ben Stiller, Vince Vaughn, Jonah Hill, and Will Forte, then you'll like this flick.
It doesn't take itself seriously at all, and you shouldn't either. It's all about swearing, drinking, and sex, but twisted from the point of view of a family man, not a party animal or a college student. So the result is a tame adult suburban version of juvenile mayhem.
It's totally brainless and each character is at best a parody of a human being. Stiller is not as his silliest and a slim Hill seems to present us a more serious approach to his comedy style with his character, while Vaughn is his wild self.
Don't expect anything more than brainless humor, and you'll be happy watching it.
