Just rewatching bits of RAW on youtube and the Finn return really highlights how great the presentation of him is. His theme is great, the "dun dun" heartbeat fulfills the iconic opening sound requirement, the lighting and entrance graphics are cool, and he comes out with his leather jacket and his arm waving that the crowd does with him, it's all really good. And that is just his regular normal Finn intro.
By contrast, it also highlights that despite all they push him, the presentation of Reigns actually really sucks. His music is boring and it's just the Shield's remixed, his entrance is boring, he just walks to the ring, his vest is stupid and there's no interesting lighting or graphics for him, etc.
I'm not crapping on Reigns here, I'm saying even though WWE want him to be their new top guy, they've totally failed to give him a really iconic entrance like every top guy has had. Rollins and Ambrose have the same problem. You know Stone Cold's entrance, you know Cena's entrance. Nakamura's entrance is a big part of his popularity, he even says so himself. Let's not get started on Roode.
