There was a Big Brother 4?
Just joking, I watched every episode, just like the other 10 seasons
I'd definitely rank it in last place of all the seasons in terms of sheer entertainment, but it was a very important series in the show's history. Without it, we wouldn't have had the huge shake up of season 5, which still to this day remains my favourite.
Oh and as for the favourite HM, I'd say Mr Tickle.
