Another aspect we haven't discussed, is just the one match good?
I know there was talk at one point of a trilogy. A Summerslam rematch and then a final match at next years 'Mania, but they seem to have gone with one and done.
Personally I like that, makes it seem more special, and if we have another in a few years we won't think, "Oh God, they've already faced each other countless times." It something that NEEDS to happen more often, I know the build has stretched so long, mainly due to Rock's schedule, but the long build, with one match rather than numerous matches is really benefitial.
