He has a lukewarm roster (Grenadier, Kiba, Nougami Neuro, Rainbow) and for a show so famous they could definitely have found someone with more interesting titles and experience to handle things.
SCRIPT I was not thrilled when I found out the director of the show would be Koujina Hiroshi. But for many it is still a much superior show for its kind, since it is not direct in its themes and definitely not one of the same shonen stuff. It was taken out of the spotlight as soon as Naruto and Bleach came around because its merits were always hinted, the artwork was very weak (manga included), and the story was left incomplete. PROPER MENTALITY This is the remake of a cult shonen show from 1999, which still remains a top favourite for thousands of people who followed it throughout the years.
