The Killing Joke

When the comic 'Killing Joke' came out, it changed everything. Comics were bright and like eight colors, the standard beat-'em-ups. This series was what Batman comics should have been, but the paralyzation of Barbara was stunning, especially when they kept it. Sadly, I always hated the reason why they did it despite that it was probably one of the best/worst moments in comics, especially since they kept Babs paralyzed for somewhere around twenty years.
