I watch most of his matches even though they maybe boring just to see the crowd reaction.loved it at especially at wm where initiallylets go cena/cena sucks and later cena sucks was dominating rocky chants
Not all Cenas matches ar eboring compared to what other may think, it just depends who he's paired up with to make him look better.
But to the question I do not enjoy watching Cena fight agaisnt heels, becuase Cena gets a bigger heel reaction than most heels now days. Thats why I fear making Brock a heel was a mistake, (altohugh people are going to cheer him anyway). At Extreme Rules people are going to boo Cena and they are supposed to boo Brock too, in reality its stupid. the heels wuill be a face and the face will be a heel.
It can be amusing to see what people will chant, especially in smarky crowds as they are always worth listening too.
