Christian Diaz’s review published on Letterboxd:
What an excellent debut for this franchise on the big screen.
To be honest, this movie starts just like any other anime-based OVA that is not part of the regular story: slow, not very exciting and just as a excuse for all the characters to concur in the same place. Even the animation looks pretty bad the first 30 minutes.
But all of this is just to set the story, and the big payoff comes with the final battle sequence: the animation is awesome, there are stakes and risks, and has a strong connection to the main story.
As a fan of the anime, I loved this movie. I can’t wait for the digital version, so I can watch it again at home.
