Survivor Woes

What is up with Survivor this season? Last night, another contestant had to be medically evacuated from the game. This is the first season that three people had to leave for medical emergencies. Is it just because this season is tougher than others or is it that they are living dirtier than others? It was heartbreaking to see James come to tribal council hooked to an IV because of an infection. On a happier note, it has been fun to see the immunity idol being a big part of the game. I was blown away last night. Amanda was such a good actress, I totally bought that she couldn't find it under the flag. This season, I think, is one of the better Survivor seasons.
