From the animation standpoint, this anime is truly is solid, no corners were cut. However, I can't say that about the story and the way it was told after watching the first season.
The villains are just terrible. Very shallow clichés, who, it seems, can teleport themselves anywhere the plot needs them just to cause MCs trouble and annoy the viewers by putting their lack of any depth or original personality on display. Frankly, I just find them hardly plausible, if you know what I mean.
Next, the story. Aside from fighting aliens or having to tolerate the few villains, nothing much is going on. It's just uneventful and doesn't leave you invested enough.
The MC's are, well, okay, but easily forgettable.
All in all, I'd say animation is the only quality feature of this anime. My wife left me alone in the TV room midway, and even I rolled my eyes more often than I would've wanted to while watching this.
