#4 Brock Lesnar vs. Roman Reigns at WrestleMania 34 (Worse)
Going from The Undertaker to the two men who hold WrestleMania victories over him, Brock Lesnar and Roman Reigns have an interesting history. They faced each other at two different 'Mania main events, both of which saw Reigns get viciously booed by fans.
The Tribal Chief's WrestleMania 31 match against Lesnar was incredible. It was a violent slugfest, enhanced by the news of The Beast staying with WWE. The two stars destroyed each other before Seth Rollins came in. He cashed in his Money in the Bank contract to make it a triple threat and won the WWE Championship.
WWE tried to crown Reigns against Lesnar three years later, but the match was emphatically rejected by the fans. The in-ring work was similar to their previous match, but it wasn't as unique anymore.
Also, Roman Reigns winning seemed like a foregone conclusion. Even with the swerve of Brock Lesnar retaining the Universal Championship, the main event of WrestleMania 34 was a major flop.
#3 Brock Lesnar vs. Goldberg at WrestleMania 33 (Better)
While Brock Lesnar vs. Roman Reigns at WrestleMania 34 was poor, the former's worst 'Mania match came in 2004. He took on Goldberg in a match that had zero passion and zero consequences. Both Superstars left WWE following WrestleMania 20, rendering the match utterly pointless.
The rabid Madison Square Garden crowd that night rejected both the men and the match. Lesnar and Goldberg got a chance to redeem themselves 13 years later. Following a successful 86-second squash at Survivor Series, the two-time Universal Champion looked to slay The Beast again.
Goldberg and Brock Lesnar engaged in a violent brawl that only featured German suplexes, F5s, spears, and Jackhammers. It went on for less than five minutes and lit up WrestleMania 33. It is the most remarkable improvement seen in a WrestleMania rematch from its original encounter.
