I just saw the film, it was amazing, exhilirating, exceptional, and I had many goosebumps during watching, definitely in my top 10 of all time. The multiverse concept wasn't confusing at all, it got laid down accordingly as the storyline progressed.
I have always enjoyed watching Michelle Yeoh since her Hong Kong martial arts films, but her multi-faceted roles in films recently made me love her even more.
I don't know how to describe the film to someone else, you just have to watch it to understand it. What I get from the film's message is there are a lot of messages, hence the title is not only for the concept of the film, but also the messages. It's really good, I have to watch this again when I'm old.
Be kind, always.
