I'll keep this short. I watched all of Kill La Kill, and had to drag myself through bits of it. This short didn't give me the same issue, and honestly the main reason for that is it didn't have as much fan service.
The characters were mostly clothed, and the story as a continuation of the original series worked well.
It was short and sweet, and I had to smile at points because the characters had finally, finally, shown signs of development.
Enjoyed this a lot more than the original series but, unfortunately, it's impossible to watch without watching Kill La Kill.
