I had never seen the Bleach series before, but I kept hearing great things about it. I got the opportunity to see this movie and was completely blown away. I was a little confused on some elements of the story, but they were easily cleared up by watching the first episode of the series.
The voice acting is incredible here, as is the animation. Everything about the movie is really well done. The story keeps you gripped the entire time, and you will wish to see more when the credits start to roll.
Definitely check this out, whether you are a big Bleach fan, or haven't dabbled in the series yet. It's a great film.
