User blog comment:Epic~00/Why Total Drama All Stars Was Such An Abysmal Season (PART 1)/@comment-1037137-20140825202210/@comment-31556666-20140826121124

Scott, Heather, Alejandro, and the "Famous Four Fodders" should stay how they are. Half of the contestants were damaged in some way.

Sierra - No longer funny, but with added creepiness, ruined in Moon Madness.

Duncan - Almost a good character due to his conflict with Mal, ruined by You Regatta Be Kidding Me.

Cameron - Dumbed down by doing villainous things for no real reason. Ruined in Moon Madness.

Courtney - Decent character for about 10 episodes, but randomly turns villainous again. Ruined in Sundae, Destroyer Sundae.

Gwen - Constantly switches between being a good character, and a bad character. Saying when she was ruined is difficult to pinpoint.

Zoey - Needlessly dumbed down. Mike mentions that his personalities are all over the place, Duncan warns her, Alejandro warns her, and Zoey has seen Mal do several weird villainous things. Ruined in Moon Madness.

Mike - There was nothing to derail. He sucks.

Wow, Moon Madness was just THE episode of derailment.
