Yahoo has an extended clip from M. Night Shyamalan's The Happening up with a longish intro from the director. In his typical fashion, Shyamalan basically sets this up to be the greatest horror film of all time. Is it just me, or do all the performances in this scene come across as really wooden and bad? I know it's not right to judge the clip without the context of the rest of the film but these seem so unnatural (something I thought Zooey Deschanel was incapable of) and forced that I don't know what to make of it.
