Well, I started watching this anime thinking "this is gonna be one more of those 70's super robot anime where a somewhat random gets chosen to pilot the robot and he shouts every move he makes and he basically just fights the monster of the week". And, to some extent, I was right, as that is what happens in more than half of the episodes, but fortunately that's not the only thing that happens. Recapitulating, the story is about a race of human-like aliens attacks the earth as they need a new planet to live, but it won't be a straightforward plot as we will havepower struggles, rebellions, coup d'etats, treason and moral issues like pacifism and obedience in the mix. So, it's an interesting story!

The mecha fights are probably the least interesting part of the show, just what you would expect coming out from Mazinger or any super robot anime.
