#5 The lazy ending
First and foremost let's get the widely known reason out of the way. The lazy ending. While WWE expected to eat up the strong performance put up by Brock Lesnar, they miscalculated the negative backlash that would elicit from such a dismal ending. The no contest ending between Reigns and Rusev had already irked the fans and a similar end to the PPV didn’t sit well with the crowd.
One might argue that Lesnar picked up a definitive win via TKO. But, the problem there is that TKO is not a legitimate end to a wrestling match. Seriously. when has being knocked out of the consciousness ended a match in WWE. If TKO had to be the case, there wouldn’t be any high spots which made Shane McMahon, Jeff Hardy, The Undertaker and lot of other wrestlers famous.
It stands to reason to believe that WWE expected the crowd to go nuts with Brock legitimately opening up Orton. But if anyone had wanted to see such a thing, they would have watched an MMA fight instead of wrestling. The other problem with this lazy ending is that the WWE has booked themselves into a corner. Apart from Goldberg, there couldn’t be anyone who can face Brock at WrestleMania and make us believe that he has a chance.
