I watched this movie mainly because of Kento Yamazaki and I have to say this wasn't his strongest role.
The movie in general has really nice costumes, locations and scenes, but the overall story is a little bit strange (at least).
There were too many scenes that were lacking some logic for me (almost all of them at the end, in the palace) which killed my high expectations. Some characters were also really strange and I didn't understand their purpose (for example the character of General Ouki).
This is not a trash, no, it's a nice movie when you just want to relax, but don't expect anything special or you will be dissapointed.
