There are a lot of things to be discussed about "Little Witch Academia"(LWA) and the anime company "Trigger" especially just after the Anime Expo 2017. And, there may be a lot of people have already discussed LWA and Trigger. LWA TV version is one of the best animes in 2017 spring season(Apr to Jun). If you have not watched LWA yet, I would recommend this anime for the following reasons.
Animation
Originally, the animation is a flip book. It is all about motion. LWA is an anime of running, flying and falling, which is witchcraft of the "animation." LWA is full of amazing motions. Doesn't this anime remind us Micky Mouse or Alice in Wonderland? LWA walks the high road of animation.
Music
Michiru Ohshima is one of the greatest composers in Japan who created various music for dramas and animes. She gives us the main motif of LWA which is very simple but very impressive. This motif encompasses all this animation in various nuance - bravely, sentimentally, and so on.
Story
LWA's story also goes the high road of animation. We can say it is a pre-established harmony. This is a dangerous approach, as people expect what will come next. But Trigger always shows us what is more than we expected even if it is the story we have already known. Such approach can be taken only by the creators who are real professionals.
If you love animation, I would recommend watching "Little Witch Academia," a Japanese "anime" recently broadcasted in Japan. This is one of the best orthodox animation since Disney created their animation 80 years ago.
