When I watched DBZ which was like 12 years ago it was epic awesomeness (I was 15 or 16). When I tried to rewatch it years later when I was in my 20s it was frustrating and at times lame. Odd how that works. I'm not really much for those longer running super-powered martial arts shows personally (although I am currently enjoying Bleach, and D.Gray-man which are more complex and less annoying) but the shorter ones like Buso Renkin, Fullmetal Alchemist, and Kaze no Stigma are gold.
