I'd agree with videopirate about that. I purchased the director's cut some time ago, but it wasn't anything to exciting. Also, i found a lot of the more minor tweaks to the movie quite annoying.
For example, certain soundtrack alterations confused me a little, and i much preferred the theatrical version's song choices.
As for the visual "chapter" introductions in the DC, hmmm, not so sure about those. I don't think they should've really been placed there. It's almost as though a visual aid is put forth to you suggesting some sort of ongoing explanation but it only really serves to complicate things.
Overall, I think the theatrical version is a better movie. It's shorter, snappier and has a far better flow to it. Also, it's relatively linear enough so that the audience can digest it how they want, wheras with the director's cut, it sort of seems as though the audience is having one major explanation hinted at throughout the movie and there's not much room for individual interpretation of the film....if that makes sense, lol.
What I mean is, when the original theatrical version came out, pretty much everybody who went to see the movie who loved it, had their own opinions on the movie and their own ideas about what it all meant. With the Director's Cut, it often acts to assure the audience that there's only one true message behind the film, and it almost loses a bit of it's magic.
