Bad writing (spoilers)

It has the cinematography, soundtrack, directing, and acting of a real movie, but the story is just ass.

When in doubt, just bring all of the plot threads to a boil at the same time and have them tie each other up neatly. Have three couples at different age levels from two families like some messed up Brady Bunch. Add the industrial fire from The Simpsons - how symbolic! Soften the blow by making the teacher not turn out to be the serial killer after all, just a whiny if sexually predatory schmuck. The rebellious protagonist is really just a borderline personality disorder tedious pain in the ass. Cutesy title cards. Remove all references to Canada for some reason.

Imagine a pants version of The Perks of Being A Wallflower and cross-pollinate with Canuck dramedy borefest Wilby Wonderful. Get ready to snooze.
