I think the abusive doctor is a bit of an over-reach. The whole dark asylum theme is way overdone. Mental hospitals haven't been dark and dreary in decades, so I don't know why film makers still think they should show them that way. It would be scarier if it were a modern, well-lit facility.
And why does patient 5 knock to say "yes" or "no" when she can nod and shake her head? That's just plain stupid, and a huge oversight on the writers.
Overall, despite the kind of cool side stories, this movie was a huge disappointment.
