I don't if this has been done before, but lets make his movies better. I say it can be easily done.
Village: The outside world is a Nuclear Wasteland.
Village: The outside world is a Nuclear Wasteland.
More significantly rewrite the plot of the first series of Avatar: the Last Airbender so that the narrative actually works as a movie. For example, it could've easily cut the entire prison break bit. It was a distraction that just ate into time. And make sure the special effects weren't an after thought: they reall let the film down.
By the time he was ruining Avatar his reputation as a flop machine was pretty well established. Changing Avatar won't save his career, the POD would have to be at the latest after Signs is released. By then he had Sixth Sense and Unbreakable and his reputation hadn't been wrecked by The Village or Lady in the Water.
Give the Aliens in Signs raincoats ?
The Village was alright the adults fears were keeping them there and they in turn used fear to keep their children with them. In the end it show that there fear was baseless if the outside was a nuclear waste land then it would justify the parents own fear mongering.
Unbreakable however should have had a fight scene with Willis and Jackson, it went a bit to long in the middle and the wimped out at the end.
