I’ve watched hundreds of movies over the years to help me to learn one language or another.
I bet you have too. Who doesn’t like a good movie? And even better if it’s in your target language!
The thing is, I don’t do it much any more.
At a certain point, I grew a bit suspicious of that stock language-learning advice that every man in the street will give you: “Oh, you want to learn [language in question]? Well, you should watch movies! You’ll get to hear how people really speak!”
