i didnt like that casey, after being kidnapped and seeing three other people brutally murdered by one of kevins alters, still had love and care for him at the end. not only did he murder the ones she witnessed, but so many after him. she cried over his death when, even with DID, he is a mass murderer. his mental health did play into the fact that he did these things, but that does not exclude him from punishment. i thought the ending was also sloppy and ridiculous. split was actually good, had a lot of unpredictable moments, and kept me interested. glass is an absolute waste of these actors talents.
