Cena is the obvious choice, but I think the three month injury so far has tempered some of the Cena Hate. Kurt Angle is so fucking good, I could watch him for two hours every week.
I want to go with either Samoa Joe or Batista, but Joe has been pushed to the background thankfully.
It's Batista, hands down. Royal Rumble, No Way Out, WM 23, Backlash, Judgment Day, ONS, Vengeance, Summerslam, Unforgiven, No Mercy, Cyber Sunday, Survivor Series, Armageddon. Every fucking pay per view this man has either been in the main event, or in a title match. It's bullshit, the guy is terrible to watch in the ring and has zero personality, and does the same exact things time and time again in the ring.
