1. The cruiserweights had never been done before, at least not on that kind of a stage. It worked because it was different and they were allowed to wrestle their own style on Nitro, not tucked away on a show that WWE has all but said doesn't matter.
2. Eddie Guerrero, Rey Mysterio, Chris Jericho, Juventud Guerrera, Dean Malenko, Syxx, Billy Kidman, Psychosis and about two dozen more.
How can that NOT be a huge success???
For next year? Cena vs. Undertaker with Cena winning title #17 and retiring Undertaker for real.
