Let’s get this out of the way first:
Basically, I expected it to be an shortened version of the standard super robot story, with some modern animation. It was not as burning as I had hoped/expected, although was sufficiently burning enough by the end. What did honestly surprise me was how vile and hateable the characters are. We’re talking about Ryoma and the gang going around and like tearing people apart with their bare hands. Then again, this is a Go Nagai work, so I probably should’ve assumed that it would’ve been full of warped violence.
Also, the most Psyduck-y part was that part in the middle where they end up in feudal Japan fighting Seimei. I still don’t get the whole point of that.
Among the G-related robot shows from the decade, I’d put it below Godannar, above Gravion, and probably around the same place as Gurren Lagann.
