There’s a fine line between quirky and creepy. I’m not sure the makers of “The Cake Eaters” (2007) appreciated that. There’s a mom who takes naked pictures of her teenage daughter (It’s not what you think!). A guy who works in the high school lunchroom has sex with a special-needs student (It’s not what you think?). A guy who’s wife passed away two months ago is boinking some lady across town (It’s not what you think…). You know, the trailer is only a minute and 47 seconds, and it pretty much shows you the whole movie. And it’s better edited.
