I decided to give the winners a ranking out of 10 to indicate how much I liked them. (from the ones i've watched)
BB6 - Anthony (8/10)
BB7 - Pete (3/10)
BB9 - Rachel (10/10)
BB10 - Sophie (7/10)
BB11 - Josie (5/10)
BB13 - Luke A (8/10)
CBB5 - Shilpa (5/10)
CBB6 - Ulrika (4/10)
CBB7 - Alex (4/10)
CBB9 - Denise (0/10)
UBB - Brian (1/10)
So yeah I only really liked Anthony, Rachel and Luke A. Rachel was the only time my favorite actually won the season. And I probably wouldn't have liked Luke A as much if he wasn't Welsh. So in general, I haven't been too happy about the winners.
