So far the trailers seem to follow the book pretty closely. I know there are changes but I really don't see the story working as well if you take that out. Plus in the newer trailer there's a brief scene where you see Andrew and Eric outside with a plane falling from the sky. It is shot low so that doesn't necessarily mean they're alone... I really don't know. Just the fact I'm excited for a Shyamalan movie is odd. To think he won't mess it up is a little too much to wrap my head around. If it was a more consistent director/writer I would say it's definitely going to happen. With M. Night behind it... I guess we'll see.
