Wrestlemania is unquestionably the biggest yearly wrestling show in North America. Routinely drawing in more than 70,000 fans, WWE's biggest attraction has evolved from a regional wrestling promotion's Hail Mary to an event on par with the Super Bowl. Cities now bid on hosting Wrestlemania and it brings in millions of dollars of revenue each and every year. However, some years the main event of the biggest show of the year leaves something to be desired. It's no secret that Vince McMahon feels he knows what the fans want more than the fans themselves. While he has struck gold with a few notable names, there have been several misfires that have come from the mind of Vince McMahon. From his refusal to push crowd favorites to presenting the same stale wrestlers in the main event slots, McMahon has seemingly alienated as many fans as he has created in recent years. With the build to Wrestlemania 31 being one of the worst in recent memory, many people believe that the Roman Reigns vs. Brock Lesnar advertised main event could be one of the worst ever. Actually, it's just another entry in a long line of Wrestlemania main events that fans really didn't want to see.
