overall, a positive reception from japan
what about /a/?

While the experience itself was enjoyable for me, I do worry this might break a 'notion' on the japanese to make animated AU Gundams that focus on making just variations of UC Gundam without worrying on contradictions to the original series, instead of more original AU series that don't require one to watch the original.
