The pictures of the ITV drama look promising. Bamber & Julie at the funeral look very similar to 1985.
Hopefully it is a straight forward A-B drama. Show the build up to & the reasons why Bamber thought he would get away with it. Followed by the massacre. Followed by the trial & a summary of the 33 years of appeals.
Making it into a 'who done it' will restrict the programme makers too much as there is so much incriminating evidence against Bsmber.
