I absolutely love this movie I felt like it was a good representation of a couple of different mental illnesses And I see alot of people say there was a Throw away ending but I disagree because I feel like (spoiler alert)the TVs popping on at the end was a representation of him hearing andy in his head repeating things to justify what he had just done to himeself. This movie represents the slow build of manic phycosis and hiw fast that can switch
Its also a intresting representation of anthropomorphism and how the human brain does infact have the ability to make meaningful relashionships with objects that WE KNOW arnt alive/actively responisive.
9/10 in my opinion.
