Bendis only cared about his characters and his favorites, pissed on everything that came before him, never gave a single thought to existing continuity, and poisoned decades worth of existing heroes for his own plots. He was horrible for Marvel and their willingness to let him jump from one corner to another of their universe just spread the bile and poison around. He is the chief reason that there is no more continuity in the 616. On top of it all, he spoke as if the comic medium never existed until he arrived.
Good riddance to bad things. My sympathy to DC.
Every character he "treated badly" was out of love.
