GROWN UPS—-a really bad Adam Sandler movie in an entire separate class of Bad Adam Sandler Movies, this is about as cheery as crime scene footage.  Kevin James, Chris Rock, David Spade & Rob Schneider join the obnoxious manchild for a kind of  Unmagnificent Five.  More talented and likable than those smug clods are the gals somehow suckered into playing wives: Maria Bello, Salma Hayek, Maya Rudolph.  Also suffering are Steve Buscemi, Joyce Van Patten, Tim Meadows and Colin Quinn.  Awful writing, direction (Dennis Dugan) and performing, yet it skunked an astonishing $271,000,000 in 2010, erasing its mystifying $80,000,000 cost and planting germs for a sequel, which was also a hit.  This kind of nothing-passed-as-entertainment chips away at the very will to live. 102 minutes.
