Possible Spoiler -
Chris Tarrant have an extended interview in The Times, and he said he was disappointed with the way the drama gives a soft option on whether or not the parties involved were guilty or not.
Mr Tarrant pointed out the the major was completely clueless in the dummy rehearsal rounds, and was veering towards several wrong answers and then suddenly changing his mind to the right ones, right up to the final question, which he was poised to get wrong, and again, inexplicably changed his mind to the right answer, which he had not even considered.
In MR Tarrant's view, the involved parties were all as guilty as sin - it remains to be seen if the drama portrays them as such.
