How true! As much as I disliked Russell Hantz I dislike this guy even more. I hope he never gets on another show. He is not an all-star. He's an insecure little baby who seems not to like anyone who looks different from him (Alicia was not his friend but just a means to get what he wanted). He may or may not be a ratings booster. I guess we'll find that out now.
There's really only one criteria for getting asked back: Is the person going to help increase Ratings
To be asked back, the person is going to fall into one of two fan catagories:
Mostly loved by fans
Mostly hated by fans
Generally floaters don't get asked backed because they just want to sit around and let the hardcore plays knock each other out of the game, but they are very boring to watch on TV because they so\do practically nothing. Floaters have won, but nobody wants to see them back.
Characters like Colton and Russel Hantz (or little Hantz), are hated by most fans, but they are the types we love to hate, and we do victory dances in our livingrooms when they get voted out. If the show was full of lovable characters, or all floaters, then Survivor would have never lastest more than 2-3 seasons.
Also note, Everyone who gets on the show has at least one serious personality flaws\weeknesses. When casting the show, the producers don't go out and only get successful people who have a high degree of self control. It if were, it would be like watching people play chess. Rarely would they say\do anything that might give away information about what they thinking or their plans. They'd all pretend to be great friends, never saying anything bad about anyone, and only back stab each other during tribel council. The entire show would be about the competitions and the vote because everything in between would be forced\faked friendships for 39 days. TRULY smart people would hold back their dislikes for others for 39 days to have a chance to win 1 million. Thus, when casting the show, they get people who easily get frustrated, are control freaks, have a short fuse, etc; basically can't keep their mouth shut for more than 24 hours when they are unhappy about anything.
