When I went to Chris' eviction in BB13, walking in, the place looked all flashy and bright but the dirtiness of the place was unbelievable. This was only at the start of BB13 and they had barely had 2 series before it, so can't imagine what it looked like outside for CBB17!
Also, i was lucky Chris' eviction even watching on screen had an electric atmopshere and i felt it there, but yeah C5 crowds have never been huge.
I mean THESE are crowds...
