I didn't mind Cena so much this year Cena/Michaels, Cena/Umaga were good although Michaels blatantly carried him. Status is right tho, no one moves ratings significantly anymore. Cena's era is basically holding steady at 3.0-3.3. There have been segments this year where Cena lost viewers Cena/Kane before EC for example was losing viewers on the reg. In fact Cena lost viewers alongside Rock in an overrun.
I don't really like nor do I hate Cena because he has an understandable role as top face as well as ambassador for WWE. I can't really blame him for the circumstances that culminated in him running with the torch but what I don't like is how the WWE halfway sabotages other people trying to get on that level which would actually help take the load off Cena. Punk last year and Bryan initially are two examples of this. The Attitude/Ruthless Aggression Eras were lead by Rock/Austin but there still was a great supporting cast like DX, Jericho, Booker, Lesnar, Angle, E & C, Hardys, Dudleys, etc. WWE today is a lot thinner and as a result Cena gets pushed over everyone which diminishes the importance of those wrestlers.
