Really, there is very little going on here - the film starts with a fantastic high concept and likeable protagonists, but squanders this almost from the get-go. The film's multiverse is in practice just a set of gimmicks, and isn't used in any insightful or interesting way that informs the characters - the conflict between Evelyn and her daughter is banal in the extreme and there are no real thoughts here other than #BeKind and love each other. The film's hyperkineticism and forced wackiness is hiding the fact that there's basically no content here. And the character of the daughter is really underdeveloped, we know almost nothing about her - the film's central conflict would have worked way better if Joy had been more rounded and developed as a character.
