Mania 27 wasn't terrible, but it wasn't good either. Punk/Orton and Mysterio/Rhodes were matches I wish had more time.
Don't understand the Miz hate though. He's got a crappy character, but he's really good in the ring, IMO. It's Cena that I wish would go away. No one annoys me more in the WWE today than Cena.
As for The Rock, you won't see him until January or something, IMO. He'll randomly show up and Rock Bottom Cena to cost him the match, and restart the rivalry. A rivalry I pray Rocky wins. He's so much better than Cena.
