“Diary of a Wimpy Kid: Dog Days” is the third and latest big screen installment of author Jeff Kinney’s wildly popular series of illustrated novels about wise-cracking but hapless middle school student Greg Heffley (Zachary Gordon). As Greg confides to his diary (though, as he likes to point out, “It’s NOT a diary, it’s a journal!”), middle school is “the dumbest idea ever invented,” a never-ending ordeal involving – among other appalling things – wedgies, bullies, morons and swirlies. And if you don’t know what a swirly is, then lucky you.
