So is there a reason the 2007 series GR Giant Robo never got subbed? Was it bad?
Best girl is kill.
It's... Interesting. I wouldn't recommend it though, even if you can understand moon.
It's very cold in it's execution. Feels more like a Nolan movie than anime. Worst offender is Giant Robo itself, you really have to wonder why he is in there, thry could have replace him with a generic mecha with little change. They don't even call him Giant Robo, not even once.
It was notoriously disappointing. Don't watch it if you're looking to recapture the magic of the OAV, definitely.
