It's good but it has some minor problems that' stem from the media that it's trying use, and some technical issues.
I find the audio/sound design of this series as off putting. As in they've left too much dead space in some scenes that could really use some. Most of the scenes were fine but with a lack luster punch to the audio. And ofcourse it is an anime with some 3d parts to it but they've utilized it well and the 3d parts doesn't take away from the animation itself.
Now with the story and all, it is very interesting. I like the plot a lot it felt like a one shot that didn't have any stutters in it's execution. Although some of Malcolm's scenes were a bit annoying because he was playing for the long game and withheld important information for most of the series.
Overall I think people would like the concept and story itself. 7.5% for a more precise rating because there's a couple of facets that could be improved.
