I watched this film that has garnered a number of awards and eleven nominations for this year’s Academy Awards. It takes the intriguing scientific concept of the multiverse as its basic premise, that the universe splits and branches at various points and hence there are a huge number of parallel universes, of which ours is just one, that have different degrees of similarity to our own depending on how long ago those universes split away and evolved independently. As far as we know, if the multiverse exists, there seems to be no known connection between the various universes but in this film, the main characters can move between them.
Given the acclaim that the film has received and that the multiverse is the driving idea, I anticipated enjoying it but found the film to be a huge disappointment. It started out trying to make some points about why some people are moving from universe to universe (because they are trying to stop a very bad person from doing some very bad thing) but about two-thirds of the way through, the screenwriters seemed to lose interest in that and instead turned the film into a fairly standard family drama involving the strained relationships in families and the way they play out in the various universes.
