I think for me, one of the most engaging aspects of the OWaW series has been the introduction of the UF-verse witches. Of course, I'm loving the handling of the original cast just as much, but the newly-introduced witches adds a breadth to the world that in hindsight is lacking from the show itself.

I recognize that, as was mentioned in the original threads regarding Strike Witches, these are 12-ep series, and there's little enough room to work with as large a cast as the show actually has; but I definitely get a stronger feeling of a "world at war with the Neuroi" here.
