*Hulk Hogan: His influence on wrestling turned it from an athletic competition where, at its best, you could suspend disbelief that it's staged and let yourself become engaged in struggle between the performers who you knew something about beforehand. Hogan was a marketing figure who played a cartoon superhero aimed at young children, and made a mockery of wrestling, while helping the WWF extinguish smaller promotions that had been members of the NWA. Later he playhed heel as "Hollywood Hogan" in WCW, and pushed the NWO angle into the background, hogging the limelight.
Other disliked performers, in no particular order:
Mick Foley
Samoa Joe
Goldust
Undertaker
Ultimate Warrior
Godfather
Trish Stratus
DDP
BTW, there was nothing wrong with Lex Lugar save that he didn't live up to impossible expectations. He had some great matches in the NWA/WCW, and was a decent man.
