I dunno, to me Reigns is akin to Randy Orton. He's dull as fuck as a babyface. His intro with the slow walk, completely devoid of energy, watching around like he's showered in cheers when in fact he's not, just makes him totally unengaging as a character, as does his work, which I find repetitive and too focused on one spot (with the WWEtm annoying super obvious setup). Like Bruce Prichard would say in his Cornette voice "He's a heel, motherfucker." Just turn the guy already, he could be so much more fun. And at one point, he'd get so hot that the fans would turn him organically. Anyway, he's been pushed forever so of course he's getting big reactions, but he's like Triple H in the early 00's. He's just not the guy, no matter you slice it. Triple H was never Austin nor The Rock. Roman isn't Cena.
They push him as too stoical at times for sure. He entrance would be so much better if he just had a bit more swagger in his walk and demeanour. And a touch of Steve Austin trash talk. Actually, new music would be nice too. An actual popular rap song is probably too much to dream for.
As for the Orton comparison, I think thats unfair to the point of slander. Randy Orton does the Randy Orton match that, depending on his opponent and motivation, ranges from **1/2 - ***1/2. Reigns has had legitimately great matches to the level that Orton never has. Hes worked vulnerable against Strowman, turning in one of the greatest babyface selling performances in company history. Hes worked as a power/bully guy against AJ, Rollins and Balor. Hes done the bloody brawler performances against Lesnar. Hes a great tag worker. Just far more variety and range than Orton has ever shown, and Im not even an Orton hater per se.
