First off, Boogiepop is a horror anime, pretty much like Elfen Lied and Higurashi no Naku Koro ni and all three shows also have a few similarities: blood, gory violence, very disturbing, great art and animation, and a dive into the human psyche. But then again, there are the differences between the three and what makes Boogiepop different from the other two is also what makes it so amazing.
What makes it truly stand out completely is the art/animation. Throughout the entire show(except the last episode), the art is done in a dark, hazy, blurry, sepia tone; the animation is good but sadly the character designs are very bland and make it almost impossible to tell everyone apart. Both art and animation are really good, but they make the show a lot more confusing the it's own plot line which I will get to right now.
The story for the show is very non-linear, if you go into this without knowing anything about it, you'll get left behind scratching your head for sure. Boogiepop takes place in an unamed city in Japan where a month ago, a pillar of light appeared out of nowhere and strange things start to happen along with some nasty murders that seem connected to another killing spree from five years ago. Actually, trying to come up with a brief synopsis for this show is honestly very difficult, so lets just leave it at that for now. From time to time, the show would focus on a certain character and learn about them and their connection to the events. Just like the works of Satoshi Kon, Boogiepop is very very psychological and when it comes to the human psyche, it goes in way deep than you would image. There are also some themes in this show such as: change, relationships, dualism, and escapism.
Finally sound; not only does Boogiepop having great sound editing, but it also has some of the best music ever composed in an anime. The music mainly consist of gregorian, experimental electronica, and mostly just sound effects made for the anime. I haven't heard much of the Japanese dub, but the english dub is really good; Right Stuf International did a great job with the dub if I say so myself.
Elfen Lied and Higurashi are indeed both great horror anime, but to me, Boogiepop Phantom is one of the most underrated horror anime as well as one of the most overlooked anime in general. I highly recommend this to anyone looking for something good and scary to watch. Multiple viewings are a must for Boogiepop Phantom.
