My list is too long. It would be easier if I wrote down who I liked...but I'll give it a go.
Big E Langston
Prime Time Players
Just to name a few.
Ryback: My least favourite superstar. Overhyped and afwul on the mic. Never liked the Feed Me More saga.
Brodus Clay: I'm just feeling his funk.. I think his gimmick is a joke and he looks like a CAW, a 12 year-old has created.
John Cena: Boring and still gets cheesier every year. Acts like he has been an underdog for not holding a title for a couple of months.
3MB: Combination of random superstars who don't have anything else to do.
Jack Swagger: Doesn't matter what gimmick, he'll stay boring. His feuds are reaaaaaally booooring..
Dean Ambrose - Needs better selling tactics. Looks like he's hurt but then fine half a second later.
John Cena - More stale than crackers left in the open air
Kofi Kingston - Has mid card belt reign to try and keep relevant
Rey Mysterio - Just give it up Rey
