I watched the first one, and I usually like a dark drama, not averse to violence! But this one scared me so much I couldnt sleep. Im retired from a job where I worked with many damaged and disturbed invidviduals, and in my view it went too far, too mysoginist and explicit. Such extreme violence and hate towards women portrayed in the letters from the suspect, and he is a very dark individual. It goes too far, and it may give men with those tendencies more ideas. Im going to write to the broadasting ombudsman with my concerns.
