I almost gave up on this one 15 minutes into the first episode, but I am glad I stuck with it. To be frank, I am not a fan of the "mobile suit" style in this anime (I know they are not mobile suits, but simplest analogy.) The SD style doesn't appeal to me, and the action and animation are something of a blur at times, which makes some scenes hard to follow. However, the story ended up being surprisingly good, with a powerful twist, and I was quite engaged halfway through the series. While I do have some issues regarding the SD style (personal preference), youmight like it. Whether you do or not, the story is worth giving a go.
