1. Brock Lesnar Defeats The Undertaker - WrestleMania 30
By 2014, the Undertaker's undefeated WrestleMania streak had started to transcend the event itself. A series of unforgettable matches against Shawn Michaels, Triple H and CM Punk had kicked the Deadman's 'Mania legacy into overdrive, his bouts overshadowing main event after main event. Brock Lesnar's emergence as 'Taker's next challenger kicked off the usual round of theoretical predictions - "what if?", "could he?", "surely they wouldn't" - but very, very few fans thought the streak would actually come to an end. For evidence that this is the biggest upset in WrestleMania history, one needs only to watch the reaction immediately after Brock's pinfall. The decision to delay his theme music for a good minute or so was a masterstroke, allowing viewers to hear the utter horror of the crowd, followed by the rarest of reactions among western wrestling audiences - stunned silence. Many were angry, and who could blame them? The Undertaker's streak was sacred, an indelible part of wrestling history older than many fans themselves. To see it brought to an end by Lesnar, a big-money mercenary who had previously walked out on the wrestling business, was heartbreaking and cruel. It is important not to fall into the trap of recognising this as a bad booking decision. Wrestling is so powerful due to the emotions it can inspire from its audience, but not all of these need to be positive. The best moments don't always involve watching a long-loved favourite eventually ascend to the top, or seeing the most hated of heels finally get theirs. Equal importance should be granted to the aspects of wrestling which result in great sadness, awe, or - in this case - utter shock. http://www.dailymotion.com/video/x1vwu5i_undertaker-vs-brock-lesnar-wrestlemania-30-watchwwelive-net_sport
