I originally watched this series in Japanese, but I've also seen it in English and have to say that the dubbers did a stellar job both in voice actor choice and timing. The story line is great as well. It moves along at quite a pace; seeing as it is only 12 episodes long there is no room for filler episodes.
Keep an eye on the opening and closing songs, lots of foreshadowing...
The first out of four DVDs in the series will leave you wanting more and with MANY unanswered questions. This series has all elements of a good, and surprisingly enough, thought-provoking action/drama series. It does leave you a bit winded after the 12th episode ends.
(If you liked this one check out: "Wolf's Rain," or "Saikano.")
Review is for the first disc. This show is unbelievably cool. The characters, action, and animation are all done very well. Jin & Joe are ex-Phantom Military personel, who've become traiters to their military brethren and have taken on the job of protecting a little girl, Soma. What's their story? What's so important about her? And why does Joe cry after kicking butt? I like what I've seen so far and my interest is piqued. So far no gratuitious sex or nudity, just filled with mystery and bullet laiden bodies, highly recommended for mature viewers.
