I'm sorry to say I got dragged to the theater to see "Lady in the Water." About halfway through, I thought I had it figured out: The twist was going to be that the movie was actually a story-within-a-story and he was making some sort of high-minded (if misguided) point about mythmaking and the creative process.
The twist wound up being that there was no twist. The "clues" I had honed in on were just painfully ham-handed movie-making. Shyamalan even wrote a juicy, extraneous part for himself as THE WRITER WHO WAS DESTINED TO SAVE THE WORLD. Who the hell greenlighted that travesty? It takes away the prize from "Event Horizon" as the worst movie I've ever paid to see in a theater. The big-budget "Godzilla" with Matthew Broderick was high entertainment by comparison. There's eight bucks and two hours I'll never get back.
