Quick, easy, a little raunchy. It's definitely Victorian before anything else. The supernatural parts are well engrained into the story. The streampunk aspects though seemed at times a little "thrown on." Like how the zombie parts of Pride and Prejudice and Zombies feel like they're kind of resting atop the story instead of actually being a part of it. 
 The heroine is a pretty strong character. Granted, she was fighting vampires and mad scientists, but I wish she had ultimately been a little less dependent on her man to rescue her. I'd have liked to see her do a little more swashbuckling herself.
