Get real guys. The film was about the McGregors and the people that flew the aircraft, the rest was infill accurate or not.
Was the campaign controversial? - yes
Was Bomber Harris controversial? - Yes
Was the programme controversial (for some)? - Yes
So what.
Re recognition - be grateful, had a monument been built earlier it would probably have been a small plinth somewhere. You now have an f-ing great thing that takes up half of Picadilly right outside the RAF Club - Bomber would be impressed.
PS My late Dad was in Bomber Command during the war and decorated for it. He was not proud of what he did to civilians in any sense and would be horrified at what is being built in London. He would say it should have been built at the National Arboretum.
