'The Happening' ain't happening

I love M. Night and his movies. Sixth Sense is one of my favorites. So I was very excited to see The Happening. And while I get the meaning, I was very disappointed. I left the theater unfullfilled. There were so many strings left hanging. And the "R" rating. Well, I won't give specifics to those who haven't seen, but it was because of gore, not language (the worst someone said was 'god damn' and 'cheese and crackers'!!
