Me and my partner started watching this about two weeks ago. We binge watch as much as we can. We have a couple of hours each evening to watch it and sometimes an hour during the day. We have almost finished series 5.
At first there seems to be a lot of sub stories. It seems very busy but once you get to know the characters you can settle in to it easily. It's a great programme. Especially if you are interested in mental health, psychological horrors or the Psycho franchise.
There aren't any graphic sex scenes. Even the murder scenes aren't that graphic at all. I love graphic stuff but this is so good psychologically that you don't really need to see much.
Well worth a watch. 8/10 from me.
