There has been 22 contestants up until now
...and numerous former Z-listers - which amount to more poeple than you could find out in Galway town centre on a summer afternoon!
and 3 people have left of their own accord. The new bloke you're referring to is Isaac, Noirin's American ex partner.
If that is the case, then Isaac's arrival sounds like the Shaun('Mario')/Lisa (and later the Nicole/Rex) scenario which they did to death last year! YAWN!
Perhaps someone left the 'production wash-up' notes from BB9 in the office photocopier tray, and a newbie is touting these stunts as 'something new and exciting' to the BB10 team!
Either that, or they are thinking that pap can be churned out if you have enough different faces to portray it. I'm sure that even the fans of "Britain's Got Talent" wouldn't put up with SuBo strutting onto their screens for 9 years doing the same thing with just a different wig on her head or a new sparkly frock!
Even if the format isn't dead, then C4/Endemol have dug such a deep hole that I doubt anything that rescue it.
People are gathering to witness the end like 'Hags' at the Guillotine. I expect Gavin to turn up soon with his knitting, a comfy portable seat, and a copy of the latest Dundee edition of 'Put Down Phrases'.
I await the end of this series!
