Exactly just sign up! Like every World Cup in football needs it's Brazil and Italy it also can't function without a first time rookie like Senegal or North Korea. It might be a total pancace like North Korea in 2010 but also a major succés like when Senegal knocket out grand nations like France, Uruguay and Sweden in 2002. And yes this is the best way to paint it up!
As for TV-series BB is good but it is like a piss in misissipi when you compare it to for example The Wire or The Sopranos and of course my newest favorites Boardwalk Empire and Game of Thrones! If it is not HBO it should not be mentioned in the context of "best tv-series"...
