Welcome to the site LG, though I'm not planning to watch this year. I thought Shipwrecked went a bit evil Big Brother this year.
I didn't like that

It seems to be the natural progression of reality TV shows.
The original concepty gets lost in a desperate hunt for new and more salacious ways to create ill feeling amongst competitors.
I gave up on Big Brother years ago for the self same reason, but I actually feel last year`s finale with the whole 3rd island was much more unfair.
rewarding Greg for his outstanding attributes as a "decent guy" was noble enough, but allowing the Tigers to decide was just plain ridiculous.
