I watched it with my wife at a fan event and we both enjoyed it. We didn't have any background on the characters or the series. I knew that it was a manga that was adapted into an anime, but that was it. While neither of us thought the movie was perfect, we both gave it an 8/10. It was exciting and beautiful, but left some plot holes and small parts of the acting seemed a bit off. However, they left it open for a sequel and we're hoping that they'll correct the small things in the next one. Definitely give it a watch if you're searching for an action movie over the next couple of weeks.
