When a press release was released when BB8 was near launch, it said '...lets hope it's as successful as BB7'
After the series of BB8 there was a comment which said 'Big Brother 8 wasn't highly as successful as Big Brother 7'
Not BB5, or BB6 - BB7
I think BB5 is highly over rated, i've been watching it on youtube, and got bored after week 2
Its rubbish, BB7 was much better, and CBB4 follows it
So the producers think themselve that BB7 was the greatest series ever.
