What isn't a movie is that most of his movies are horrible.
If you mean "what isn't a myth," I'd tend to agree, but I think that's mainly due to his scriptwriting rather than his directing. After Earth
is a movie where he wasn't the creator or head writer. He did a draft of it, but he didn't shape the story and didn't write the final credited draft (though he did have the option of altering dialogue during filming). So my hope is that this movie will have his strengths as a director without having his weaknesses as a writer. If we could have that, a Shyamalan who focuses on directing and entrusts the writing to other, more capable hands, then he could still have some good films in him.
