As someone who didn't even know Pure OCD and intrusive thoughts of this kind existed before watching Pure, I found it an eye opening and also really enjoyable watch. Although it's advertised as a comdey, I'd definitely say it has a good balance between comedy and drama. It's often difficult to find humour in and around mental health disorders with sensitivity, and without coming across as condescending or patronising - this doesn't appear to have been a problem for Pure's producers.
Also great editing and acting. Would definitely recommend.
