I just wanted to reiterate that Amy and Paul missed the mark on their summary of this film. The entire film is from the perspective of an “unreliable narrator” that is in a delusion. He isn’t presented at all as sympathetic, he thinks of himself, the humble narrator, as sympathetic. Also. after his suicide attempt, he is back to his old self; therefore, he is “cured” of the treatment, not “cured” by the treatment.
