I won't be seeing The Happening for many reasons:
1. It's not based on What's Happening (Rerun is not involved).
2. I don't much care for suicide as entertainment.
3. I don't much care for really sucky movies as entertainment.
But there is fun to be had in the mocking of really reeeeeally bad movies. But even then, you have to watch them, right? Wrong. Christopher Orr of The New Republic has a spoiler-intensive guide to the most dumbass moments in The Happening so you can mock without enduring the film itself. Whew!
