I'm a bit of an oddity when it comes to watching anime. I judge a show based on how well it immerses me into it's world and how deep the story is. When I watched this, I thoroughly enjoyed it. The story was fairly deep and wasn't very predictable like other animes I've watched. The art style was interesting and well executed, with the 'quantum' effects really hitting right how it should. The sound, while not particularly special, was used to further emphasize the emotional impact of scenes and the mystery of the quantum realms. The characters were a little typecast at times, but despitetheir personalities being a bit trope-y, it never felt forced.

The main thing is that this is a slow-burner story, not some long adrenaline high like most mecha animes. Theres more time spent on creating the world and telling the story than mech-versus-kaiju fights, which makes the fights hit a little bit harder. It's pacing is slow and methodical, but that isn't a bad thing.

If you go into this expecting action and excitement in excess, you will be disappointed. However, if you go into this with a goal to experience a story deeper than "we have mechs and there are monsters to kill", you might find yourself enjoying this a lot more.

Going a little deeper, the lore explaining the quantum mechanical 'magic' that goes on in this story resonates surprisingly well with actual quantum theory, although handwaved a fair bit to make it more digestable for the common audience.

The only real complaint I have is the way they ended the story; it was a bit abrupt and felt like it was forced into a direction different than the story was heading up to that point. It still closed everything up nice and neat, but it felt a little bit like a deus ex machina. The ending dinged my score of the story a little bit, I would have scored it an 8 for story otherwise.

If you like an intellectual story that forces you to think a little bit instead of vegetating on the couch (or wherever you watch anime), then you would probably like this.
