Besides having one of the cooler names for a show, Boogiepop Phantom is one of the more complex shows I've seen. I really do need to do another viewing to get more of a feel for what is going on. Over on Anime On Dvd there is a wonderful Thematic Analysis of Boogiepop Phantom. For anyone who has seen the show it's a very interesting read (at least so far, I'm about halfway through it).
