Cara before he was injured got huge reactions. Not Cena or Orton huge, but pretty big for a mid-carder. That was with his music, that was without talking, that was without holding a title, and that was when he lost matches to wrestlers like Christian.
Imo, the real reason he isn't getting those kindof reactions now is because he does the same thing week in week out. The same springboards, the same hurricanranas, the same moveset. Usually what's popular about a high flyer/luchador is there moveset. When the people aren't entertained by it anymore they have nothing, unless if you're able to "connect with the fans" like high flyers/luchadors like Rey rey and Jeff Hardy.
