i think it is 1 of best shows on tv. of course most of it has artistic license because its not like rush where they can sit the royal family down for a detailed interview. so the conversations are made up but actions like aberfan are realistic
but you can get the gist of an episode of how things took place, i liked the 1st episode of series 4 where IRA waited until he released a lobster back into the water, until they blew lord mountbatten to bits
