I think the film is plenty long enough. I don't really wanna see a longer version. Longer isn't always better, not even in Horseshoes or grenades. Movies over 3 hours give me leg cramps, over active bowel syndrome, hair loss, dry eyes, tearing, night sweats, crossed eyes, blood clots, acne...
Some folks on the AVS Forum complained that the film was on a single disc. They contended that it was too long for such. I'm happy with my copy. It's a huge improvement over the DVD. The audio improvement was so damn obvious.
