I can see why people hate Daniel Bryan, because his current character is just not good, IMO. He comes across as the direct Punk 2009 rip-off, and people realize that. Of course, no one can't deny his in-ring skills, but for the Sesame Street world of WWE, he's not the best option for the main event on regular basis, at least not with this kind of booking. His promos are decent, but not very good.
I love DBD, I watch him since 2002/03, and it's a damn shame WWE won't let him be the heel he used to be in 2006. He was one cocky motherfucker, people hated him because he was so good, anything he said - he could back it up in the ring, which just made you hate him more.
