Normally 2D and 3D don't mix well together in western cartoons that I've watched from the past. However, this anime surprised me because I actually didn't mind both 2D and 3D blending in together!
Anyways I thought this anime series was quite good for a change. I wasn't really finding it scary but it had intense scenes where Kei and Kaito were trying to escape from the government from getting arrested and being tortured for experimentation. Mostly they really wanted Kei because they basically discovered he is an "Ajin" where his kind is said to be types of monsters with invisible powers. Although the boy didn't even know himself that he was an ajin so it does add the tension to the story.
The anime is not really the best in my personal opinion but it does the job in bringing good thrilling entertainment especially having great English Dub actors such as Johnny Yong Bosch and Bryce Papenbrook.
