'The DUFF'

a CBS Films release

Rating: PG-13 for crude and sexual material throughout, some language and teen partying

Running time: 1 hour, 44 minutes

All teen comedies owe some debt to John Hughes and Amy Heckerling.

The milieu of suburban teenage life that they explored decades ago has defined the genre since. The social divisions, the boredom, the dances, the irrepressible awkwardness and the irrational dreaminess of high school students never before seemed so accessible, and so neatly packaged with a perfect soundtrack -- even if their scope was rather limited to a particular set of middle-class students.

It's no surprise that we continue to tell slightly different variations of the same story. There are still outcasts and bullies and war stories to be told from the halls of suburban high schools, and every generation deserves its own silly teenage misfit story. While it's neither as biting as "Mean Girls'' nor as sweetly referential as "Easy A,'' the earnest and sometimes amusing "The DUFF'' is a fine addition to the canon.

In the film, Mae Whitman stars as Bianca, an overall-wearing overachiever who's just trying to navigate her senior year alongside her two best friends Jess (Skyler Samuels) and Casey (Bianca A. Santos).

But their dynamic is not equal, the handsome, popular and sweetly dim-witted football player Wesley (Robbie Amell) bluntly informs Bianca at a party. Bianca, he explains, is the Designated Ugly Fat Friend (aka "The DUFF'') of the group. She's the one who goes unnoticed till someone wants to gain access to her comparably more beautiful friends.

On its face, with the popular guy teaching the misfit girl how to fit in, it's like "Can't Buy Me Love'' in reverse. Or "Some Kind of Wonderful'' in reverse. Or even "She's All That,'' but without the bet.

But then director Ari Sandel takes a modern turn. In "Mean Girls,'' chaos ensues when the queen bee makes hard copies of the secret-filled and reputation-destroying "burn book.'' Here, Wesley's vindictive on-again, off-again girlfriend Madison (Bella Thorne, taking her "Alexander and the Terrible, Horrible, No Good, Very Bad Day'' brat to the next level) just has...
