When I started learning French, my tutor advised me to watch their movies with subtitles, without dubbing. By the way, I was able to do that and learned the language much faster. Do you watch movies online in the original language or with dubbing?
Personally, I find it more convenient to watch with dubbing when I'm watching a movie in a language other than English. However, one of my dreams is to learn Japanese so that I can watch anime online. On Fmovies https://fmovies-movies.com/ I sometimes try to understand this difficult language and watch in the original language with subtitles, but it's very difficult and requires a lot of attention, so I quickly give up and use dubbing to fully immerse myself in the story.
