Anybody who thinks this film is about multiverses really misses the point. The multiverses are simply metaphors for the more "successful" or exciting lives that we sometimes dream that we might have had. To quote the summarising lines "Here all we get are a few specks of time where any of this actually makes any sense". The reply is "Then I will cherish those few specks of time". So the meaning of life isn't about success or glamour or achievement. As the film says in life "Nothing matters" (or nothing really matters - like Freddy said!). So life is about relationships and those few "specks of time" when we share with others the magic moments that make the.golden memories that define our lives. Just a few magic specks of time.
