Bea Hamill completely, when she went in she was like the favourite to win instantly and everyone adored her and fell in love with her. Within a week people wanted her blood.
Freddie obviously he was the strong contender the whole way through BB10 - up until near the finishing mark when he started getting cocky and arrogant, thinking he was somebody and then the public turned on him.
Tom O'Connell he went in and everyone was like 'OMG MIKA! xo' and loved him - but then he became a dull bint who bitched his way to the semi final.
Kathreya Kassopi don't need to explain - but by God her downfall was amazing.
John James Parton everyone loved him at the start, he was the fit lad that bitches wanted - and just a ******ing legend in his own right. I still loved him to the end just for the fact he put that Whale Josie through a hard time, but then everyone turned on him for that reason exactly.
And the one man who went in as a hate figure, a 'repulsive being' and someone people just thought was a disgrace who should leave, but then went onto becoming the greatest housemate of all time and being adored by the public.. clearly someone who could of won had he of made the final..
