That's practically the universal language though. If only you could learn Japanese the same way in Anime.
I tried watching all of my favorite movies in Spanish.
Believe it or not, watching movies and shows in Spanish actually helps (if you've seen the movie before or can tell what's happening). But honestly, it depends on what language you aim to learn and how close it is to languages you already know. If you want to learn the Romantic languages (Italian, Spanish, Portuguese, etc), then it's best to take up Latin first (Latin is the mother of those languages).
