So many seasons have been played, people know the game inside and out. Regardless how many recruits they cast people have figured out that voting with the house works.
From now on for a majority of the game I think we'll have blow out votes.
fighterman I think because they can do more with the game and idols are always making things interesting.
Big Brother is such a basic format and not much can be done because only 2 people can go home unlike Survivor where anyone can go home (besides immunity holder) which makes things much more interesting since there are so many options. Oh and don't get me started on BB recycled competitons, Jeff being used on the show now, and the horrid twists.
