if you hate reading, dub, if your fine/love reading sub, i like sub, as the comment above me said smile
Um... the comment above you was a troller looking for gold. Still, my problem (as such) is that Fullmetal Alchemist is a well-drawn anime with action going on all over the screen. Do you know how many cats are popping out of scenes, or odd things fly through the air when Ed's on a rant if you are trying to read sub-titles? Well, maybe you do, but I get a smidge distracted. Also, there's no Mignogna-ness in the Japanese. (I know there's a lot good there, but--!)
Sub all the way. Reading+watching doesn't bother me at all. Besides, I've watched enough anime to have a decent enough grasp on what's going on without the subs. Hilarious: When May Chang says 'huge mass of chi,' she says 'ki no katamari.' Like. Katamari Damacy. I lol'd.
