Crying, mourning the loss of the humour (and sex appeal) of the house!
I think it's going to be bad for BB that one of their stars left so early - there is an empty feel to the house, and I forgot the BB round up was on last night, so I only saw the last 20 minutes. I think ratings may go down a bit, as there is less to watch for some people, and it wouldn't surprise me ifthe producers found some loop hole to shove Spencer back in the house.
I can't speak for everyone, but I wasn't loving the series before this - I liked Spencer, Kate and Jonny (when he wasn't being so serious) and now one of them has gone, and the others aren't shown a lot, I'm not all that fussed on seeing it. The rest of them just grind on me (although Jade is good to watch)
On the upside, i don't think its cause for major concern - I havent noticed much of a difference in busy-ness.
