Some of the things that made Bleach a great series for a short while was it's premise, world-building, and cast of characters. With the exception of the two protagonists that so far work really well together, this story has very little to support what they contribute to the whole. Kubo is always going to have a knack for strong characterizations, but there is too big of a flaw here with it's premise.
There is a very strange mix of modern technology introduced here as well that doesn't seem to fit with the tone of the series where we are given little to no backstory on Ninny; ultimately, a distraction away from the more interesting and otherworldly aspects.
