Cameron Diaz's flagging career is slightly recharged in this predictable but energetically crass comedy. She's convincing as a venal, lazy, drunken teacher who is aggressively trying to snag herself a rich man.
That'll be Justin Timberlake's creepily earnest fellow teacher, Scott. Except goody-two-shoes Scott is quite taken by Lucy Punch's Amy, a prim teacher full of "zany energy". There are at least three decent gags here, but this satire lacks the heart and Jack Black spark of School of Rock and the bite of Election. John Michael Higgins's dolphin-fixated principal and Punch's Amy are pretty enjoyable together, though. And Diaz is trying very hard. C+.
