can't really have a top 4 of something there's only 4 of
but for me it goes:
BB13 > CBB8 > CBB9 > BB12
This year's Big Brother had amazing housemates, really good tasks early on and although the production's sort-of weaned lately it's been a massive step up.
CBB8 again had great housemates but relied a little too much on Jedward and Kerry buzz... I liked the majority of them, though.
CBB9 was the start of a return to Big Brother at its finest but the final result was so overwhelmingly awful that I cannot rate it highly.
BB12 was a ****ing mess from start to finish
