#2 Ending The Streak
Five years after Brock Lesnar ended The Undertaker's famed two decade long undefeated WrestleMania streak, that booking decision still makes no sense whatsoever.
The win did not make Lesnar any more over than he already was and The Undertaker has never been as popular since.
Any booking decision that ruins the aura of a bonafide legend, with no upside at all, has to be considered a monumental failure.
Taker's undefeated streak that began way back in 1991 versus WWE Hall of Famer, Jimmy Snuka was a highlight of any WrestleMania card and a key draw as fans lined up to see if anybody could end that incredible run.
However, no one actually wanted the streak to end. The fact that the decision on the result was only made on the day of the card by Vince McMahon himself tells the story. Rarely has such a huge decision made on a whim proved successfully.
The booking move did not benefit Lesnar, Undertaker or WWE in any way. What a disaster.
