Yeah it really sucks that the end of this season came down to a starvation game between Britt and Sam, because that was a game that Sam wasn't going to lose, considering he was the fattest person in this season. It's basically the same reason he lasted as long as he did in the first season.
I mean, good for him for winning after coming so close the first time, but anyone who competes on this show in the future can now be sure that all they need to do to win is to go into it weighing 50 pounds more than anyone else and just lay around 90% of the time. If you're fat, as long as you have a decent shelter and can ignore your mind telling you to go home, you'll easily outlast at least 2/3 of the contestants.
Britt deserved to win though.
