I'm a Shyamalan fan, yes, but I'm surprised at the love for Lady in the Water I'm finding in this topic. In any case, here are my takes on the films by him that I've seen:
The Sixth Sense
Easily one of my top movies that I've ever seen. The way he told the story with the cinematography was just incredible, and Bruce Willis and Haley Joel Osment (one of the best child actors EVER) completely stole the show. The plot twist, though everybody knows that it's going to BE there going into the movie, caught me and everybody I know completely off-guard, and overall the movie was just completely mind-blowing.
Signs
Wasn't a big fan. Yes, I liked Mel Gibson, I thought he did a splendid job, but I was expecting to be scared, and that didn't seem to be the point of the movie. It was more of a... sort of ominous feel the movie had, but not exactly frightening, if you take my meaning. Good movie, but nowhere near Shyamalan's best.
The Village
I actually loved this movie. Not as good as The Sixth Sense, but it was frightening enough to keep me on the edge of my seat, and overall, it was actually cinematographically his best-told movie. Technically, this movie was excellent, but it just didn't have the aesthetic feel and the superb acting that The Sixth Sense had. Still an excellent movie, though, that I would give a high rating to.
Lady in the Water
All right. What the hell was Shyamalan thinking with this movie. It was so bad I was laughing at it the entire way through... it was interesting in the way that a car crash on the side of the road might be interesting. You stop and watch it, and are interested by it, but after you leave, you say, "That was just awful," and are done with it. If you want to read my full review of this pathetically bad movie, it's on Amazon, if you select to read one-star reviews only, it's the seventh one down (for now), and it's written by "Kyle Bolme".
I've never seen Unbreakable or Wide Awake, but they're both on my list.
