I guess I will start with the basics. Does it hold up even now? I think this is a good question to ask about this anime, since it was aired in 2011 for the first time. You might say that it wasn't too long ago, but it has been almost ten years and in the anime industry a lot of things can change. But no worries because it still holds up pretty well. Yes, you can feel the gritty feeling that a lot of anime titles had back in the day, but otherwise I think it held up pretty well.
Though I cannot say it's perfect. I don't really know how to exlain it, but even though the anime was pretty action packed and there was a lot stuff happening most of the time, it still felt like it was lacking something. It felt like it needed some more umpf to it. Like, some of the episodes felt plain. Of course, story wise, the information you're getting is not bad, it's just that it feels like nothing is going on sometimes and this was my biggest issue with it. Another problem that I might have, is with the main character, since a lot times, his decisions just don't feel realistic at all. I know it is possible that it's part of the story and it's meant to be like that (because some characters do mention his attitude), but still.
Now for the good stuff. The story was so well written that you don't know what to expect and not only that, it is kinda written in a complicated way too. Which you can notice only after finishing the series, including the one episode that came out a year after. But, it makes sense and without it, I guess the anime wouldn't be so good or popular. The artstyle was also really good, the only problem I have (personal preference I guess) is the color palette, that they use. I just don't like it. It feels like 50 shades of gray, but only in a literal sense XD, but, fun fact, in the episode that was release a year after, it was changed. ANYWAY, the audio was well done, I like the first OP song the most, it was really good and I think it showed a really nice preview of what to expect from this anime. So, for the most part, job well done!
Finally, I give this anime an 8/10 because it's not perfect, there are some unpolished corners left to fix. It's good, but don't expect too much from it, since there is stuff that you will want to go through as fast as possible (possibly from boredom), but if you get to the end, it will be worth it and remember to also watch the extra episode, that came after (trust me it will be worth it).
I hope this will give you some insight on it and have fun watching it. PEACE, I'M OUT!
