K and Deckerd's fight would have been avoided with a normal dialogue. Joi didn't have to be "canceled". Madam didn't have to die. Why didn't they tell the story of the "Memory Maker Daughter's" illness? They did K dirty making him believe that he was the miracle child. A lot of bad behavior or outcome of the Replicants' might be avoided by making them in a spesific and certain manner and quality or make them look the same, etc. Too long time yet too little was told. Waste of opportunities...
