#2 Wrestlemania 33 Main Event
The longest tenured WWE Superstar, The Undertaker is perhaps the most respected Superstar. A perfect way to put heat on a Superstar is to have him face The Undertaker.
There's absolutely no chance that the fans will ever turn on the Deadman. So, what caused WWE to book The Undertaker vs. Roman Reigns as the main event of Wrestlemania 33? Maybe it was done to pass the torch from Taker to Reigns, but that didn't turn out so well.
The Big Dog ended up defeating The Phenom in a decisive fashion at the Show of Shows. The outcome, followed by Reigns' appearance the following night on Raw, was met with an outburst.
The reaction was so loud (in a negative way) that Reigns wasn't even able to start his promo for a while on Raw. The video of Reigns' promo on the Post-Wrestlemania Raw emerged as the most disliked WWE video at that time.
All it can be said is that the outburst was a guarantee and even the top heels of today struggle to receive that kind of reaction.
