[Wasted]

For me, it is the best series, BB6 is my second favourite but the other 3 series I've watched (4, 7 and 8) don't even come close.

The tasks were WAY better than they have been the last two years, as have the twists, and the housemates were way better too. It didn't have too many housemates neither, there was only one newcomer, and there weren't any "filler" housemates who do nothing (well, some might argue that Vanessa, Stuart or Shell were fillers, but compared to more recent series, they were quite big characters), whereas now almost all the housemates are fillers with an exception of about 3 or 4 people.
