Math question: What's the lowest common denominator times five? Give up? It's the new Adam Sandler comedy, "Grown Ups"!

Sandler has assembled a roll call of actors who make comedies for people who consider Judd Apatow to be too highbrow and brainy. Kevin James? Here. David Spade? Here. A slumming-it Chris Rock? Here. Rob Schneider? Oh, god, he's here, too.

The quintet plays a group of childhood friends who reunite after the death of their junior-high basketball coach. Lenny (Sandler), now a powerful Hollywood agent, rents a lake house for the friends and their families to unwind.

Joined by inexplicably hot wives (Salma Hayek, Maria Bello) and kids attached to cell phones and video games, our humble heroes all learn a little about life. All the while, hilarity ensues.

OK, look, I've been doing this movie critic thing for a number of years now, and I'm familiar with the defenses of Adam Sandler movies. I know my words won't change anyone's mind on the matter.

The comedy is low-end sitcom level. Fat guy vs. cheap swimming pool. Tongue-kissing an old lady. Falling face-first into poop. Oh, sorry. Spoiler alerts.

There's a place for this mindless comedy, but the problem with Sandler movies is the tendency to try to attach a supposedly emotional story. No exception here.

The childish stuff is fine - if not particularly funny. The problem with "Grown Ups" is when it tries to act grown up.
