Enjoyed the docu . I think it probably held the interest of the viewer throughout, which would be one of the objectives of the producers.Agree with other posts that it did not shed much new light on the causes , but then it's a legal minefield out there for anyone speculating . I thought JH was doing fine until he came up with the proposition about the fire going out ,like ,of it's own accord .What did he mean by this?. Did not come across to me as plausable and did tend to undermine the rest of his case.
