I'm still not entirely convinced Shyamalan has the chops to pull off something so different from his usual oeuvre.
Judging by his last few attempts at film making, perhaps his "usual oeuvre" is the thing that isn't working for him. TLA
's amazing characters, setting and story are being handed to him, he merely has to edit and frame it and do what he's done well most of the time even when he made a bad movie: make it look good. The trailers are certainly promising on that front.
It's quite unlike any other project he's worked on, maybe it will be good for him to play in someone else's world for a change.
