These are 2 multiverse anime movies that are related to each other. They were released on the same day at cinemas in Japan. So there's no particular order to watch them. People are saying that the ending changes according to the order, and that it's sad one way and happy the other way. But not exactly. Is it happy or sad? Well, I don't know whether that'll be a spoiler or not so let's just not.
Now to the main question - how are these movies? - I'd say they're fine, but nice enough that I don't regret watching them.
The idea is still very interesting and the storytelling method is cool. Because the story of these 2 movies complete each other. And I don't mean they complete each other horizontally (like your normal sequels). The stories are parallel to each other while, from time to time being entangled in each other. So there are many cool story moments when your mind's like - "oooooh I see now". And when I think about these movies and their stories together, it's pretty cool.
But having this structure of storytelling, makes these movies - individually - very confusing. And the way they explain the multiverse phenomenon is very confusing too. I'm not going to keep pausing the movie to understand every confusing sentence in it. You have to make your Sci-fi elements simple enough for your audience to understand. Steins Gate did that brilliantly. And the movies are lacking some energy too - in terms of voice acting and soundtrack. There are some redundant scenes in the 2 movies too - like 10 minutes worth.
Overall the stories are heartfelt for sure, and the romance is very nice too. But it's definitely confusing. And if I'm being honest, I'm probably going to remember these movies just for the storytelling idea.
