He didn't get himself over. He got pushed to the moon and back.
No he wasn't pushed to the moon. He lost all of his important matches and was put through 6 tables in 2 1/2 months.
The only actual "push" he ever got was CM Punk bouncing from the ring a few times so Ryback didn't touch him. You can't call the title matches a "push to the moon" when he lost them all.
You're just throwing that term around to be melodramatic and exaggerate the fact that he was only used as a temporary replacement for an injured guy (Cena). Ryback never had a chance of winning and was booked to lose every step of the way.
You don't seem to know what "being pushed to the moon" means. Last time I checked, it actually included winning important matches, not losing them all and being repeatedly put through tables to appease the fans who hate him.
I've noticed Cena fans damn near everywhere think this same thing. They hate great workers like Kidd, love horrible workers like Ryback. Go figure.
I don't think he's a Cena fan.
He's a WWE fan who wants to be excited and entertained when he watches the show, not be like "hmmm yes, that's a nice maneuver", but otherwise have the same stern look on his face throughout the show since there was nothing to mark out for.
How in God's name is John Cena third most charismatic when half the fans hate his guts even though he's supposed to be the top babyface? And heck, if this week's Raw is any indicator, a lot of them don't even have the energy to react to him anymore.
It's not actually "half", it's just that the people who hate him are the loudest and most obnoxious fans of the lot, so they whine about him the most and are the main people who chant negative chants.
I'd guess it's closer to 15-20% that hate him, not 50%.
