I enjoyed Rick's showboating the entire game. He played hard and used every advantage that he could find/was given to him. He also created enough confusion with the others to get them to make some pretty boneheaded moves, in retrospect.
I also came to like Chris, in the hour or so I saw him on the show last night. I have no recollection of him before last night, other than a vague idea that he was the hot guy on loser island.
Gavin, Julie, and Victoria left little to no impression on me. I was impressed that Lauren managed to hang onto her idol until the last possible moment.
As much as I dislike the idea of someone from loser island returning at the last minute, it did introduce an interesting dynamic in re jury management at final tribal. Still, I hate the idea that someone that was essentially out of the game for 30 something days was able to return at the last minute, and was handed an advantage, over the others who managed to not get voted out at all.
