This one was actually a big miss with me.
Things I didn't like:
1) I am actually kind of bored of the idea that dead people want to cause harm to others just because they're dead. What's-her-bucket was devoted to her husband - why would death make her want to deliver some kind of asphyxiating dirt-kiss? Zombie stories I can get, because they usually include some explanation of the method of revivification as imparting some anthrophagic imperative, which means that it makes sense when dearly departed Aunt Susie tries to nom on your noggin. In this case, however, the jar o' magic goo was supposed to bring her back to life. Obviously, it didn't, which resulted in a horrible parody of life, but... the story didn't do the work. Why does horrible parody of life = eat her husband?
2) This one is going to get me in trouble... I'm a bit over "mysterious and Asian magic" as an explanation for everything. It's pretty lame. I think that relying on such a simplistic "oh they're foreign so they're magical" trick is kind of a crutch, and I prefer things that are a little more complicated. Stories like The Prince of Flowers get a free pass because they do more to make the character's entire situation (being a kleptomaniacal museum employee) interesting and consistent with the "exotic" magic that eventually shows up. Here, it felt kind of lazy.
So, overall the story was kind of predictable and under-written. What was there was good, and I appreciated the details that established the characters and fixed us in the time period. They were well conceived and well accomplished. Overall, however, this won't be much more for me than another zombie/ghost/oops horror story, consumed and forgotten.
Relatedly, Anthrophagic Imperative is the name of my new cover band.
