While I agree, this sounds like a weird complaint but The Rock has been too good, in that Roman doesn't look as impressive
I don't think that's a weird complaint at all; I agree with you totally. I think that beatdown should have been Roman Reigns's to give, not only because that is the actual match, but also because he would have done it more heelishly.
Roman has looked good by being very aloof during this run. He has been relatively calm and then he explodes. The Rock has done the explosion here and there is a fair bet that Roman is 4th or 5th most impressive in this whole buildup. Rock has, with more freedom, levelled everyone for star quality, Rhodes has continued to look like a star and the kind of man you can use to carry the company at times, Rollins has bent over backwards to make multiple leaps of logic work where I'm not sure anyone else could, and Mcintyre has been a revelation (I'm not sure why I say this because he has largely made everything work since his return, but he's been next level lately).
Reigns has looked relatively lethargic by comparison with not quite enough time to really play at a Rock and Roman relationship tension only hinted at.
And I am still all in for Rhodes vs Reigns, but I can't help but think this has stumbled slightly in, what I hope, is the final inning of Roman's reign.
Cos by god I want Rhodes to win, but I want him to absolutely murder The Rock more. And I'm not sure that's the right balance.
