So when this was airing I heard it was pretty good but I put it on the back burner & completely forgot about it until it popped up on Netflix. I heard it was a similar theme to "Madoka Magica" which is one of my favorites so I was very confident I'd enjoy this before ever starting it. Right from the go my first thought was "wow! The animation & art style are great!, this is going to be good!" And sure enough shortly into episode one the main plot opens up, very similar to "Madoka" as I've heard. I was kind of thinking "man..I hope this isn't basically a total rip off of it" but its its own story even if it has its similarities. The story is about these young girls that have to fight & destroy these "vertexes"(basically giant monstrous entities) whos goal is to destroy mankind. The story is extremely character driven, you get a real sense of connection with everyone of the main characters. None feel left out which is great. My only complaint with the story is it doesn't explain certain main information very well, especially in the beginning, but because of that its a show that you can watch 2-3 times and notice things that you completely overlooked on your initial watch. The artwork, animation, & character design are all amazing. Some of the most beautiful stuff your gonna find. The music is great, everything matches the scenes so well & the OP & ED songs are so majestic, very pleasurable to listen to over and over. The show ends very good, it could end here and be satisfying but if you look up any information about the visual novels & light novels you'll see that its been completely left open for a prequel & sequel, so I believe the lack of information in season 1 would be completely covered with a continuation regardless if pre or sequel. If you were a fan of "Puella Madoka Magica" or other darker themed shows you can almost guarantee you'll enjoy this, its much darker than it appears. Definitely not aimed at children.
4/5 Why? Great animation & artwork, pretty decent story with a lot of potential(highly suggest looking into the light novels & visual novels after finishing, the amount of story that we've yet to see is just awesome). Great music & songs. This is one show that you can guarantee you'll notice things you didn't catch at first if you re- watch it. Fan of dark themed stuff with epic fights & battle scenes(really all the scenes lol), this is for you.
