I've watched the whole thing and I thought it was very good. Sure - the attitudes of the time towards the victims and towards women in general were horrible. Such sexism, misogyny, victim-blaming and utter, disgusting arrogance. The way all the detectives were laughing and congratulating each other when Sutcliffe was finally caught (by another police force) after five years of bungling incompetence by W. Yorks Police was appalling.
I thought the way the women's stories were told was good though - they were humanised, the women who were prostitutes were treated sensitively and the reasons why they turned to prostitution and still had to go out on the streets when they knew the ripper was out there were well explained IMO. As for the locations, sets, 70s cars, wallpaper, clothes, etc - spot on as far as I can remember. The paisley pyjamas that Denis wore in one scene were exactly like a pair my dad had in green - I'd completely forgotten about them until I saw that scene.
