I don't think this show is obscure at all. If he wanted to talk about obscure Transformers show, any of the Japanese ones that have never been localized, as well as Car Robots, would be much less talked about. Also Rescue Bots. Or just any Transformers things that aren't cartoons.
Anyway I never watched it even though it was super popular because the designs all pissed me off. I can accept Optimus as a trukk or a munkey but not as a Jay Leno. Also, his vehicle form still looks like a space vehicle, as do some of the others, so I don't buy he's in disguise at all. Also, while I never watched it at the time, looking back in retrospect, seeing the main character is an indian girl doesn't fill me with hope that it doesn't have proto-sjw shit going on. The humans were always awful in Transformers anyway, and I just want more shows with no stupid humans. The cavemen from Beast Wars were the closest they ever got to not being awful, and they were barely human in the first place. Just like the one from Animated, I suppose.
