The series was very slow and child-like in the very beginning...but about halfway through it was CRAZY AWESOME! The plot thickened with every episode and the cliffhangers were outrageous. The animation is beautiful, and it captures science fiction in a very realistic perspective, as opposed to the usual sci-fi that just has stylized robots and space ships. The character development is interesting, but really the show is all about how creepy the technology is. I can honestly say I am thoroughly impressed with Denno Coil. NOT what I expected at all.
