I've never watched an anime before (and some of you will probably bash me for that), but I would like to begin on one that has short episodes, is over and is overall, short and beginner friendly.
Bonus points if Historical.
Pic is unrelated.
Series: Full Metal Alchemist Brotherhood, it's not short and I'm sorry about that but it's perfect entry level. Great dub, has a splice of all genres, never met someone who didn't love it. Do yourself a favor and stream it.
If you refuse to then go watch One Punch Man, it's only unpopular on /a because it's well relieve by the public. Action comedy, 12 episodes, superheros.
Movies: Wind Rises, Sword of the Stranger
