After nine years away, WrestleMania returned to its birthplace and the site of some of its most legendary moments - the New York City area. Though it wasn't Madison Square Garden (the home of WrestleManias I, X, and XX) East Rutherford, NJ's MetLife Stadium, just west of lower Manhattan, was a perfect place to host one of the most anticipated rematches in WWE history - The Rock versus John Cena, part two. The bout was a follow-up to the previous year's show and huge "Once in a Lifetime" main event. At WrestleMania 28, The Rock pinned John Cena in front of his hometown Miami crowd and appeared to have won their intergenerational feud. When John Cena won the 2013 Royal Rumble match and The Rock captured the WWE Championship at the same event, the stage was set for their second showdown. With CM Punk versus The Undertaker and Brock Lesnar versus Triple H as semi-main events, the company was able to set a new live gate record of $72 million. That didn't change the fact that the show drew mixed reactions from fans and critics alike, though, and three years later, many of the plans that WWE put in place that night have proven to be mistakes or were quickly changed. Looking back at WrestleMania 29 there are 10 things we can assume WWE would rather the fans forgot.
