I enjoyed the first three series, but it seems to being getting a bit silly now, especially with all those B celebrity's trying to look passionate as they are taking part in a so called serious competition between Ant & Dec.
Never have been its biggest fan but it was very boring Sat night. It would be better if like you say they had some decent interesting celebrities on there.
I must admit that as far as Saturday night TV goes, this is entertainment. Not great, but watchable all the same. I would much rather veg out to this (no concentration required) than the dreary and depressing Casualty or the dire Who Wants to Be A Millionaire.
I agree about the celebrity thing though. I don�t see why they need to have any at all. How irritating was Paris Hilton!
