Alex in BB12 was the main one. It seriously annoyed me how her fake persona had people thinking she was lovely. Luckily her mask did start to slip, but I was amazed that she kept it up for so damn long
Glyn is another, I did not understand how everyone seemed to see him as this innocent child.
Jackson I could not stand. He seemed liked by the general public but hated on here, so not sure if he counts
Josie I liked on first impressions, but couldn't stand her by about week 2. And yesm, I am still bitter about the stupid quad decision that lead to her winning too. She may well have won without it, but the stupid decision cemented it tbh. We
could have had the most unpredictable final ever.
