What was the first anime you ever...
watched?
That takes me back quite some years now. I can't recall if Sailor Moon came first or if Pokémon came first for me. I definitely remember watching those two shows early as a kid though; like around five or six years old. Not too long after came shows like Digimon, Cardcaptors, and so on.
watched knowing it was "anime"?
I didn't even know what anime was until my freshman year at high school. Before then, I always categorized them as cartoons. ):
watched subbed?
The Melancholy of Haruhi Suzumiya. I started watching this in the middle of 2009, and when the second season came out, I began watching that subbed since it wasn't out in English yet.
