I actually wasn't disappointed at all. My thoughts were similar to JR's at the time, "AWWW, SON OF A BITCH!".
You know what would've REALLY been disappointing? They reveal who it is, and it's some nameless rookie WWE decided to push for awhile (aka some shit you'd see nowadays).
Yeah, imagine the alternative. Vince being the higher power was far, FAR from being anywhere close to the worst thing that could've happened. Vince was always a great heel.
Though I can tell a lot of people who were pissed about that were Taker fans. I kinda wasn't, so maybe that's why it didn't bug me at all.
The Corporate Ministry Days were fun though.
