I'd give a 8.5 if I could. This anime has one of the most cool characters I've seen in anime, Hei. The dude's attitude carries this show, but that's not to distract from the other characters. All of the main four, even the girl who rarely says a thing (I really enjoyed the episode focused on her) are a blast.
The series is done in hour long vignettes, something not normally done in anime... and it takes the creators a little bit to get used to it. The first 7 or so episodes of this show were average and forgettable, but give DTB time and it finds it's place. Keep in mind, the beginning episodes are still necessary viewing for the mood and background it sets.
So is the beginning rough? Yes. 7.9 worthy? Hell no!
I know many a anime viewer such as myself who see's a score under a eight and thinks the show is a pass, but listen up. DTB IS NOT A PASS. This shows has everything to love in a anime and the ending WILL leave you satisfied.
I love these characters, I feel the thought in the writing, it is complex and has a philosophical message. This one moment near the end delivers some of the best symbolism I've seen. Truly this show is a powerhouse; a world in it's own. Even characters who come in for a few episodes have a grand purpose in the study of Hei.
Do not miss this show, it will have a impact on you and entrance you in pure coolness.
8.5/10
