I always think of 07 as the last season of the 10 era too. I remember 08 vaguely, I didn't think it was that bad as it was one of the first seasons I rewatched (started from the bottom) but as I watched the other seasons it was pretty bad in comparison to the others. The hosts were bad, I hated the stage, the house was one of the ugliest, the diary room was nasty and it was confusing. I remember that stupid show when they had to dig for something in the backyard and I think that was when I realised that 08 had hit rock bottom. The casting was ridiculous too, they went for stereotypes (midget, Aboriginal, blonde bimbo, grandma etc) instead of interesting people. It had some good moments and some clever twists but it was a bit of a fail :\
Edit: Oh my god and does anyone remember that magician that came into the house and the housemates had to act as if the magic was real!? WOW THAT WAS EMBARRASSING.
When Carson came into the house that was pretty stupid too
