"Welcome to the new-look, high-risk, high-speed show,” said presenter Chris Tarrant at the top of the programme. Well, sort of new-look; the opening titles are new (although they still haven't managed to put the question mark in the logo), but the music is the same and the set appears to have had no more than a dust down since the last series. But let’s not quibble, as producers Celador have indeed rung the changes and in doing so have given the long-running show a much needed fillip.
