Adam Sandler cast a bunch of old buddies as his old buddies (Kevin James, Chris Rock, Rob Schneider and David Spade) and reunited with director Dennis Dugan, whose long-running collaboration with the Sandler dates back to 'Happy Gilmore.' You'd think this thing would yield more organically generated laughs. Grade: C.  

Don't let the title of Adam Sandler's latest movie fool you: 'Grown Ups' is as juvenile as anything in the actor's filmography. At 43, Sandler remains mainstream America's go-to goof-off, a guy whose perpetual adolescence has made him one of the most successful box-office stars of the last 20 years.
