M. Night Shyamalan's New Movie Will Make You Want To Kill Yourself

Twisty mystery auteur M. Night Shyamalan has a new movie coming out, and it appears that he's not trying anymore. Why does it appear that way? Well, for one thing, his new movie is called The Happening, a title that is second only to The Wha?!?, and The Whatevs in terms of both description and effort. Secondly, the movie is about people in New York City killing themselves for no real reason, and, well, we already have that movie. It's called Cloverfield. Except in Shyamalan's version, the monster is the environment (this is apparently his "green" movie) or something else that will be revealed in a third-act twist you would have seen coming had you stayed awake.
So, what will The Happening's inevitable, surprise twist ending be? Here are a few ideas:
—It's all fake! Everyone just pretended to kill themselves in order to help Mark Whalberg hone his scientific skills. You're welcome for your education, Mark.
—Everyone was secretly listening to "Suicide Solution."
—There's a magical girl from a lake whose mere existence makes everyone want to kill themselves.
