This is so good, it was comical and so stupid at first that I did not even expect myself to be crying over a rock pushing another rock off a cliff. The multiverse concept felt more like a means to the end, it was a good way to lead the film to where it was going. I'm not sure but I don't think we are meant to take the multiverse part seriously hahaha. I totally recommend this movie. I wasn't expecting to like it as much as I do now, maybe cause of the mother-daughter dynamic that the whole thing showed.
