Worst finalists ever (was beaten by BB11's final though)
First case of a Housemate being taken outside of the house, old housemates returning for tasks etc.
The whole Noirin's boyfriends/whatever being put into the house was one of the worst producer decisions of all time.
The tasks were largely poor (and the launch night twist - changing names? wtf?)
Many rubbish housemates as well - Charlie, Rodrigo, David, Sophie, Kris and Cairon were all terribly dull.
