I've heard of this anime before, and also heard about how mixed everyone was about it. And I've understood why. The animation itself isn't bad, it looked rotoscoped despite not mentioned to be. I think what made it jarring was the lack of SFX in EVERY scene, like the destruction lacking dust cloud, or when people are hurt there's not a splash of blood. The OST is also lacking and doesn't add to the atmosphere, especially that first fight scene. The writing hasn't shown its muscles yet, but this is still the first episode, let's see the next one.
