I'm not familiar enough with the genre to give this a real rating, but I really enjoyed this show start to finish.

"Strength can fight a war, but it can also build a shelter."

If you haven't watched any of this, do it. I'm really not one for anime; most of it really annoys me and I think it's super embarrassing. Usually it's full of logical faults that are only explained by "it's a cartoon, let it go." I'm not good with that and they really irk me. This one, while not entirely free from it, does a really good job of being consistent. It avoids all sorts of anime tropes in fact and it's incredibly refreshing in that way. It feels much more substantial than most shows of its ilk. The whole show has some SERIOUSLY excellent fight choreography, beautiful animation, thrilling violence, truly funny bits of comedy, and genuinely interesting and moving characters. Conveniently, not a single one of them feels the need to scream any of their dialogue, cry excessively, or creep on every female character that exists in the show. The voice acting is top notch, the story is solid throughout, and by the end of it, you just want more even though you've walked away genuinely touched by the final moments of the epilogue.

Like I said, I'm not one for anime, and this one is quite good. If you haven't watching any of it, start at the beginning and chew through it. It's worth it. If you have watched it and just haven't watched Season 4 yet... hurry up because it wraps up quite nicely. I have my issues with parts of the epilogue where I feel easy choices were made instead of poignant ones, but that's a pretty minor complaint.
