Update on Dragonar:
Apparently Funimation censors their version (they cut out an entire 2 minute scene from even the broadcast version), plus they have really shitty raw quality (obviously lower, and not just HS's fault).

The AT-X version doesn't look nearly as bad, though it is still not great. I'd put it at 2010 art now. If you are going to watch it, watch the FFF version.
