The story is good, the synopsis explains that this anime has potential, and the plot itself is indeed interesting. This anime has VERY slow pacing, you will find quite boring for the first few episodes(boring until episode 12 I guess?), but you will get hooked by it. One thing that I didn't like in the story was the concept of mechas being used, it didn't fit really well with the story. This anime also brings deep messages to its viewers, but it doesn't convey well straight to the point and can't connect its meanings to the viewers completely. With some deep messages it brings, this anime has psychological undertones and contains some explicit scenes which may not please others.
The characters were really good, we can see leaps of character developments as we go on with the show. At first they seem pretty forgettable, but they kinda grows within you. That feeling when your first impression on a character changes, you will like them and eventually root for them. Some supporting characters may be dull, one-dimensional, and their actions do not make sense, but you can see their developments as the show goes on. Also, one thing that I also find it interesting is that this anime isn't afraid of losing its characters, characters that didn't stand out at first evolved and developed pretty well(especially Mhamu), character interactions, some characters were just so crazy and insane(the mad scientist LOL) but their presence is really essential for the plot.
The art, for a 2014 anime, was quite cheap and a little bad. Maybe the studio were on a tight budget for producing a 24-episode anime or something, but it still fits the atmosphere of the show. The use of dark colors really sets the dark mood of the show. Character designs were fine, the mecha is also good I think, having consistent animations and distinctive designs. CGIs were satisfying enough to entertain our eyes throughout the show.
For the sound, which includes its music and sound effects, were pretty good. I really find the openings catchy, the first one "Re:Remember" by May'n fits with the sad tone of the show and reminds us of a beautiful sorrow, the second opening was "Replica" by Sakamoto Maaya, was really catchy, giving us hints of how the series will end but the animation of the anime spoils its viewers.
"Ego-izm" by lalalarks is not that appealing for me...at first. But eventually the song, piano keys, and its music gets stucked in your head. The second ending song "SABLE" by nano was my favorite, it really conveys the action genre of the series. There is only a small set of soundtrack, but it still gets the job done. Character voice acting were just average, they didn't stand out.
As for my personal enjoyment, the first few episodes are not that good, to the point of being boring or even bad, but I assure you watching the episodes continuously can at least change on your point of view to this anime. For an action anime this has less action, but more on character interactions for summing up the plot, but it's still good. For those who dropped this, give this a chance.
Overall, I give this anime a 9. It think it deserves some praise, the show was pretty successful itself in terms of adaptation, it's really sad, as the anime itself didn't do anything bad to be hated, that people dropped this, this isn't even worse than other mecha animes out there, so give this a shot.
