One of the few things I actually consider myself somewhat knowledgable in (even though I can't spell). I liked Full Metal Alchemist, I thought it was plenty dark and angsty, but not til somewhat later in the series (been a long time since I watched it though).
07 Ghost has been ok, I'm somewhat behind in my anime watching, but it's definilty not the best, I agree.
Hikaru no Go has got to be one of my FAVORITE series. I can honestly say I've read and watched the anime at least 3 times each. I would KILL to have good Sai/Hikaru/Akira pairings and such. Complicated love triangles...hmm....makes me wish I had even the slightest talent in writing!
