The 'kids learn english from movies' line is just insane. Yes they learn it from movies, and music, and books, and the internet, and etc. That is how it works. A lot better than duolingo in fact (Free yourself from the terror of the owl, you have been keeping your streak for over year and you still can't speak the language well enough to watch a movie. Streaks, progress bars, challenges, making the app sad, experience points, achievements, shit thought up by the utterly deranged).
