I consider myself to be mixed on director/writer M. Night Shyamalan. I enjoyed THE SIX SENSE (although it only took the trailer for me to figure out the surprise ending) but grew increasing disappointed with SIGNS, THE VILLAGE and LADY IN THE WATER. And while I've yet to see "his first R-rated movie" THE HAPPENING the negative reaction it received from moviegoers and critics alike isn't very encouraging. To me his strongest film was the cool-as-hell UNBREAKABLE which I also consider to be one of the best comic-book movies (origin or otherwise) ever. Recently Shyamalan has been mentioning doing a sequel (of what had been a planned trilogy and had this to say:"I want to write it right now, but I want to write it for the right reasons. I want a story to pop into my head that is organic and expressive of who I am. You know, these are all kind of journals of where I am emotionally, so it's kind of hard. I'm kind of trying to go back to the journal that existed in 1999 for me. But I know me: As soon as I give up on it is when the idea will come to me. It's just I need to go into therapy; I guess that's the end of that answer to this."
His somewhat peculiar response will be of no surprise to anyone who has the fascinating book THE MAN WHO HEARD VOICES which followed the director's struggles to get LADY IN THE WATER made. In it Shyamalan is shown to be quite, to put it nicely, "quirky" in nature. I strong recommend it as a read.
