Don't get me wrong, I like watching it in Japanese, too, I just have to do it when I have more time. It takes a lot more concentration. Hard to explain--you'd have to see the way my viewing area is set up. For one thing, if I use dubbing I can sit back on my bed and watch, which I prefer; whereas if I read the subtitles I have to sit at the computer, which is less comfortable; or else I have to go in the other room with the big TV, which is comfortable but then I can't work on anything in my room at the same time, which I like to be able to do when I'm watching stuff.
The opening for SP is cool, though I'm still trying to figure out the lyrics. Is the FMA one online?
