Great plot The plot was quite unique and shocking, but the fish looking lady was very annoying throughout. I think they most definitely should've chosen another actress for that role. And the ending too. Felt like they're implying she is the monster given how much lack of empathy she shows. The rest of it, I'd say the characters were very well written and well played.
It was the kind of movie that makes you think, and moving forward, affects how you move through life. How you view and treat the people that provide us with a service, specially if it's a passion of theirs. And how much we value the enjoyment of one's profession, among other things.
