The directors cut isn't bad. It's a great improvement, most of the new scenes add charactor and the pace is different and better, less jerky editing. It should also be noted as an interesting side note that this cut (unlike other 'director's cut) is in a way a fan edit, by the director. Firstly, unlike a film like Blade Runner or Kingdom Of Heaven, where a different kind of film was invisioned then what was released, Peterson went back and changes the style and tone after the fact. The second case bieng that in some cases sountracks from other films is used, for example during the fight with Pitt and Bana, The Danny Elfmen Theme to Planet of the Apes is used.
