In BB7, it was obvious who was going to win. No matter what online bookies were saying, we all knew Pete was going to win from Day 1. Okay, Glyn was a close second and Aisleyne a close third, but the other three in the final...well, it was obvious they stood no chance of winning.
In BB8, we all knew it'd be a Samanda/Brian final. Jonty certainly stood no chance, neither did Carole. Ziggy and Liam were obviously going to be third or fourth...but the winner was quite predictable as to which two it would come down to.
BB:CH came close, with the final four coming as an absolute shock. Anthony fourth? Amy third? EMILIA SECOND?! Nathan and Jeremy were obvious as to who would get 6th and who would get 5th, but the final four of BB:CH came very close. Shame the BB interview format got screwed up.
Now, in BB9 I think that all 5 remaining housemates actually stand a chance. I wouldn't be surprised if there are some silent voters out there who vote for Sara just like they did for Emilia, or vote for Darnell although everyone on here dislikes him. Now that Mohamed and Kathreya are out of the way (and it was obvious that they both stood no chance), the finale will be a complete surprise. I'm actually looking forward to this finale because I don't know what will happen!
