Murder in the Village: Who Killed the Doctor's Wife?

I seldom give 1 star, but this is ridiculous. There is nothing new in this documentary, no new information, no "secrets". The first parts gives the info about the case, which it repeats every ten minutes after a potential ad break. And then the second part *repeats* all that for 20 Minutes! And in the end, you gain nothing except what you already knew at the beginning: a doctor probably killed his wife, they couldn't prove it, he died without being found guilty, that's it. There was evidence the police didn't use, but why they didn't use it isn't examined beyond "we didn't find the witness reliable". Why? We'll never know! Infuriating.
