I can't speak for the other HM's, but i know Tom is happy with the decision to air earlier then planned.
It gets a lot of the attrention out of the way early and i think the main thing is, it's not such a long wait till January, that was a pain, filming it all etc etc then having to wait several months to see it.
Tommy & Jade have gone to 'The Salon' today for treatments

not sure when that one will be on TV
I have my comments about the HM's but i tink it's safer if i keep them to myself being related and all.
It's kinda hard not to have a biased opinion.
When this series has finished and Friday, it's not all over. Channel 4 have done some extra filming which will be shown in January, the general gist will be: What did you learn, how are you coping now etc etc
