I've seen some criticism that it was a bit sensationalist. I don't really get that. I think sensationalism is partly based on intent, not just content. I don't really see a negative intent here. It's not to designed to shock for the sake of it. OK, so maybe they could have left out details about some of Beth's food behaviours (episode 1), and maybe some SH stuff. I'm sure there's a lot that's already been left out. But I didn't have an issue with them showing that the staff search for sharps, or the showing of scars. When people were restrained this was generally shown at a distance rather than having the camera shoved in their face, which seemed respectful whilst still showing reality.
I get the feeling that for some people the perception of a mental health hospital is a padded cell, straight jacket and patients drugged up to the eyeballs. This is not that. Yes, there are protocols to protect staff and patients, including more acute cases, and it's a controlled environment, but there is still some liberty that they can at least be themselves to a degree.
In a programme like this you're always going to have to make difficult choices. I'm not sure they have explored each patient's issues in-depth, although they give accounts of each one's circumstances...there still seems to be something missing to maybe explain the triggers, etc. That said, there needs to be a balance between giving people time on camera and not pushing too much.
I like how, in Beth's situation, we see the duality of her personality. The more rational part and then the distorted, automatic eating disorder thinking, and the conflict between the two. You've got to feel for the families who are also putting themselves on camera.
