Edward is a gaslighting, manipulative sociopath....and anyone who knows a sociopath would know that any type of therapy will NOT help or change them! They're far too wrapped up in themselves to change, because in their eyes, they're already perfect! (Episode 4 sees him in the therapists room)
I've got so many negative things to say about this drama, but they've already been said by previous posters. A huge waste of 4 hours of my life.
