Characters look samey, especially the girls. Everything is stiff, slow and boring animation-wise with the sole exception for the fight/gore scenes. Watch a compilation of the gore on YouTube or skip through this entire thing to get to the good parts.
It missed a massive opportunity to make it about two delusional, demented victorian zombies going on a vengeful killing rampage slaughtering everyone in creative and obscenely brutal ways. (This still happens, kind of. It's not in the cool, well paced and mature way you're hoping for inside that brain of yours sadly.) Too many long scenes of talking, walking and nothing happening that bring the pacing to a screeching halt. Oh and some pointless martial arts scenes for padding it out before the inevitable, I guess.
That makes it... a... hmmm... 2. 2 out of 10 yes. 1 extra point for the short lived gore scenes that should've honestly set the bare minimum for gore standards in anime. Newsflash they almost never reach this visceral level even today because people are cowards and or lazy.
