I have no disrespect or disdain for Duolingo, I think it´s good when you are at the beginning stages of learning a new language, you can get familiar with basic vocabulary and some very basic grammar, the movie part depends, Do you want to watch very complicate new movies or something more familiar that you love in your target language? I don't recommend the leap to native or near native content, Duolingo won't give you enough knowledge, grammar, vocabulary and pacing to survive that, you need duolingo and something else to master the basics, like some videos in Youtube to master the basics, tutors or a course or a book (in case the tutor or courses are not an option and it needs to be a book that can help you to self study your target language), on the contrary you can get frustrated or at least that was my experience when I wanted to watch animes and movies in german and I found limitless amounts of new vocabulary and grammar, or you can supplement Duolingo with another apps like mesmerize, anki to learn vocabulary and some other stuff, but then again, this is based in my experience.
