Need I remind you that your statement is only valid for Joss Whedon Shows, because in my opinion, his work on non self created properties is far less than stellar.
I liked Connor, he was kind of badass lol. And he wasn't that bad in season 5 was he? Dawn is the most unbearable character in the show though, and it didn't help that Michelle Tratchtenberg is one of the worst actresses to ever be on television...
