I remember Halloween Havoc '98 being pretty damn good.
EDIT: And Spring Stampede '99. Fucking Blitzkrieg, man.
Watched both of those recent, HH '98 last night....It's not that good outside of a very excellent main event. The two disco inferno matches were pretty good and so was the Jericho/Raven match.
Stampede 1999 has a good hardcore match and a great opener and then the rest goes to shit rather quickly.
