The Director's Cut is the only way to go.
Watched what a studio can do to a film. They wanted a less dark Salt and they got their studio film.
Thank God Sony gave Philip Noyce (great director!) the chance to show us fans his version. It is far better and way darker and sinister.
This cut is on the blu ray and to me is the preferred cut from making a decent film to a great film. 8/10.
