I may like their music or admire their acting chops but I don't really love or hate any celebrities- eh, whatever.
But I have a deep and enduring resentment towards Bobby Brown and the path he led Whitney Houston down. It was physically painful watching her walking corpse try to sing near the end.
Compared to the angelic voiced and amazingly beautiful young woman he corrupted it always throws me into a rage when it comes back to my attention.
