Don't forget Poison Ivy. At first it looked like they were going somewhere by making her an anti-hero, but when they made her turn bad again, it was just one step forward and two steps back with her stupid new costume.
DC is a corporation trying to make money, they don't hate any of their characters. We all have favorite characters that have had things done with them that we don't agree with, but don't imagine a grand conspiracy to ruin your favorite character and wrong you personally.
Black Canary, Tim Drake, Harley Quinn, Dick Grayson, Joker, Starfire..

Fine, This will explain my problems with Dick Grayson.
And Joker, he lost his personality, he's just plain Evil now, the new joker is like "SIT THE **** DOWN BATS!"...the old Joker makes you question your own sanity, he had irony on his side, but, the new Joker, is just a "Evil, Evil man", excuse me while I'm going to cut my face off just for the sake of it.
