He's a pretty bland director
This is not a criticism of the writing or characters to his films, though there's plenty of issues there, but as a filmmaker he really doesn't do a whole lot behind the camera or gets much from his cast or crew. He doesn't do anything unique with his shot selection, staging, or sound to his films and just places the camera statically getting very basic shots of his acting talent. At best, his style of filmmaking could be described as "lightly-edited improv."
Why the lack of creativity?
