I agree at least you would know basic sentence structure or uncommon words. Its also helps you read faster since you must finish 1 sentence at that particular moment.I've learn a lot of language from reading manga/watch movie. I know how to read how to listen. But a real problem will happen when you speak with real one even talk from phone. lol
I'll have to agree like that. If you're learning a foreign language, watching anime/manga isn't the best way. That's at least what my Japanese language teacher told me when she said that some people learn Japanese listening to Japanese music and it comes out horrible.Studying abroad would probably be one of the best ways in learning a foreign language.
