At the 2015 Royal Rumble on January 25, Reigns was booed heavily after his victory despite portraying a heroic character. In February on "WWE Raw", Paul Heyman praised Reigns as better than "any other guy in history", which garnered negative reactions as Heyman stated esteemed wrestling figures, including Bruno Sammartino, Hulk Hogan, Andre the Giant, Stone Cold Steve Austin, The Rock and John Cena, were inferior to Reigns. By March, Anoaʻi altered his character's physical appearance by wearing contact lenses in order to have blue eyes. From late 2014 to early 2015, various critics raised concerns that Reigns, despite being "not fully ready", was "being pushed too hard, too soon" while WWE tried to make him their next "flagship star", "no matter how fans reacted". Anoaʻi reacted by saying that he only entertained criticism of his wrestling by people that were involved with wrestling, discounting negative opinion by critics that "weren't wrestlers" and who wouldn't understand how to "lock up". Going into WrestleMania in 2015, Dave Meltzer said that Reigns was the least over WrestleMania main eventer ever. At WrestleMania 31 on March 29, "Pro Wrestling Torch" described Reigns as needing security for his entrance while receiving "universal boos" and middle fingers. Reigns was unable to defeat Brock Lesnar for the WWE World Heavyweight Championship after Seth Rollins cashed in his Money in the Bank contract and pinned Reigns to win the world title. Rollins received positive reactions for his victory despite being a villain. Despite the fan backlash in early 2015, critics praised Reigns' performances at Fastlane, WrestleMania 31 and Extreme Rules as exceeding expectations while the negative reactions continued at Money in the Bank and SummerSlam.
