How Do You Judge Directing/Acting

I understand what you're saying, but its not completely accurate. Every director has his/her own style. As a matter of fact the greater the style the better the movie often is.

For example: You would never confuse a movie directed by Quentin Tarantino, from Michael Mann, from Stephen Spielberg, from Brian DePalma, from Terence Malik, from the Coen Brothers. All have distinct styles that you "notice". As a matter of fact that's what we like about their movies.

The "main" job of a director isn't to hide his/her style, is to make the movie seem as if it couldn't have been told any other way but their own.

Do you think if Terence Malik or the Coen Brothers had directed Raiders of the Lost Ark that it would have been the same movie? I guarantee you it wouldn't. They'd have different directing styles that you'd "notice".
