The characters are abysmal. Over the stretch of all 13 episodes, the main characters never get any sort of development or depth to them. They're just as bland and one note as they were when they were first introduced. For side characters that'd be acceptable but these are main characters, they're supposed to be carrying the show. Each character is defined by their one trait. Tsubame is the outcast with the tragic past, Yuumi is the genki girl who wants to be heroic, Satoka eats, Io is the athletic girl, and Mana is complete head over heels for Io. The characters never grow to be any more than these traits. In fact, they felt more developed on episode 1 than they did at the end. It's amazing how little variety and growth these characters got. They spend all their time being into their traits, being nice to each other, or fighting the Obli. Oh, the Obli. It's amazing because the side characters actually get more development than they do. Characters that get introduced half way through the show get more development. Although that development is pretty much the most conventional and cliche development to happen. As soon as their roles are apparent in the show it's clear how things will end up. Furthermore, they never develop beyond that. Their depth isn't explored either. This show only tells you as much as needed for the characters. Which in almost all cases is not the way to go about characters.
And then there's the plot. The plot pretty much the blandest and most generic plot one could think up of. Even though there is most to the plot than what it starts out it never gets developed or interesting enough to be worth any time. For the most part, the story is about these girls (and other girls) fighting off these monsters in another dimension. However, these monsters have such bland designs it's underwhelming. The other dimension also looks pretty fake. It reminds me of a 2000 quality cyber world. Furthermore, the show likes to waste our time by doing things like classifying the Obli into different types and the like as if that would add any interest to the show. When the show is riddled with so many holes spending time on trivial details like that gets rather annoying.
The main art is alright, but as stated before anything to do with the other dimension is riddled with uninspiring art. The sound quality is passable I guess? There's nothing that the OST does to make it stand out, which fits in with the rest of the show. There's simply nothing here that lets the show stand out from any other show.
Through and through the show is not interesting in the slightest. The best thing about the show is the relationship between Io and Mana which isn't even a vocal point of the show. It's just part of Mana's character. There's nothing worthwhile to be gathered from this show. It doesn't even torture the user because it's more underwhelming than it is terrible. This really is genericness the show.
