I think I will watch this season, after having stopped watching years ago. I also disliked Rob in his first season but he won me over in All-Stars and in his first season on Amazing Race especially. He is extremely smart, strategically and socially, and overall far more ethical than Russell. Other than the first time on Survivor, he really has dominated. When he did AR all-stars, they were on a tear with at least three first place finishes until they lost in one of those stupid find a needle in a haystack challenges that are completely unfair (other good teams have also been ousted on such stupid pure luck challenges). On the last Survivor round, I thought his ouster was also unfortunate.
Of course, I will root against the idiot Russell but notably they won't be interacting much at the beginning. If the contestants were smart, they'd keep Rob around right up until the merger for his game play (but by then he will probably have charmed everyone). I like the idea of redemption but I feel like for sure Russell will go there and then only return to wreak havoc. I think there has been too much Russell in the last few years (Rob's stints are much more spread out) but how could the producers resist reprising the Rob v. Russell battles.
