American movies/anis/dramas/etc for learning English communication?

I don't know of the proper speaking speed. You'd be better off in school learning to speak proper English.

BTW not sure how this is an R&S question, but oh well. Each nation has to settle on a standard national language. In America it is English. In Japan it is Japanese. In France it is French, etc etc. It is impractical to think any nation can learn and operate, making every sign, book, and every show on TV come out in EVERY language spoken in the world. A Stop sign would be a mile long. Even then you'd probably complain that your native language was not the first on the list. Granted everyone should be flexible and be willing to learn another language if they need to. And people are shallow and make fun of each other from childhood on, so what do you expect there? If you want to live in another nation, you should learn its language and not expect the entire nation to revolve around you and learn yours. That isn't practical.
