Finally got around to watching it.
Like in the first movie, the visuals are magnificent! Just something that I noticed right at the beginning again
I agree with @Blue Dragon about probably everything Still don't know most of the names as well. What I also found kind of a let down was Chizuru's role. She seemed to occupy a much more active and important part in the first movie and this movie didn't really do anything. @Blue Dragon why did they even include here, right?
Generally, I thought her whole family (father and brother) could have been developed a bit more. They disappeared quite quickly.
Also had hoped that more people would survive but they probably wanted to stay close to the actual history of the Shin Sen Gumi.
What I did like though was that they explained quite a bit about Chizuru's father and his plan, and also about how that magic water works. I thought it was quite well made that you have to give up your life energy for it. And, I also thought it was great that they showed a lot more about the devils' side and their perspective of things. Oh, and finally they showed why the movie is called Hakuoki
So, I'd say overall it was decent, but felt rushed quite often. They should have made the movie two times that length and really developed everything a lot more. But just like @Blue Dragon I think I should watch the series
