IMO, the quadruple eviction in BB11's semi-final week was the single worst creative decision C4 ever made.
Yeah, worse than BB8's all-female launch. Worse than putting Nicole into BB9 or Isaac into BB10. Worse than BB10's "non-houseguest" twist. Hard to believe, but it was even worse than allowing Nikki (and the other ex-housemates) to go back into BB7.
A final with John James, Corin, Josie, and Sam Pepper would've been epic, and a slight consolation for the fairly crappy series we had to endure that year. There's no clear winner out of those 4, any of them could have walked away with it.
But the 5 housemates we ended up with made it the most anticlimactic final in BB history.
