Katherine Heigl, Josh Duhamel, and Alexis, Brooke, or Brynn Clagett in Life as We Know ItLIFE AS WE KNOW IT

Rob Schneider, Chris Rock, Kevin James, Adam Sandler, and David Spade in Grown UpsGROWN UPS

In basic outline, director Dennis Dugan's Grown Ups is similar to last autumn's Couples Retreat, that witless, odious comedy in which a gaggle of Hollywood stars enjoyed a luxury weekend on a tropical isle and demanded that audiences pick up the tab. (More than $100-million worth of ticket buyers actually did. Staggering.) Beyond their locales, though, the main difference between them is that Couples Retreat starred Vince Vaughn, Jason Bateman, Jon Favreau, Faizon Love, and Malin Akerman, while Dugan's film top-bills Adam Sandler, Kevin James, Chris Rock, David Spade, and the entertainment vacuum known as Rob Schneider. Was this Happy Madison production - written by Sandler and Fred Wolf - going to pull off the borderline-miraculous feat of being the lesser of the two movies?

Jaden Smith and Jackie Chan in The Karate KidTHE KARATE KID

The opening scenes in director Harald Zwart's The Karate Kid remake, with the preternaturally confident and magnetic Jaden Smith taking over the Ralph Macchio role, are really good. But your first indication that the movie might wind up being really great - or, at the very least, a really great time - comes with its introduction of Mr. Han, the Pat Morita substitute played here by Jackie Chan.
