Is watching german movie and tv show good for learning?
how should I try it?
I would say yes, it is. One thing I would recommend is this; when listening to music in German, take the lyrics in German, and lyrics in English, or whatever your native language may be, and follow along with the lyrics. It helped me a lot when I learned. If you can get a hold of any movies in German, watch it in German and put on subtitles in your native language, or visa versa. watch it in your native language, but put German subtitles on. They won't always be accurate, sometimes not even when the movie is in German, and the subtitles are also in German. If you have Netflix, there could also be a larger number of movies and tv shows to watch in German.
I do not know which country you're in, so I do not know if this is available there, but, look for 'Dark' on Netflix. It's a German Netflix original series, and it's amazing. Kind of slow to start off with, but, watch it. It'll mind make you a little crazy, but it's ❤❤❤❤❤❤❤ amazing. They've got it in multiple languages, but I recommend watching it in German and using the subtitles you're more comfortable with. I watched it with German subtitles to better help me grasp the full concept, because sometimes, even though I speak fluent German, some accents throw me off.
