I think watching movies and series is a great way to learn a language. Doesn't matter if it's Games of Thrones or Friends.----Alexander

    I agree with Alexander. I think the dialogue  and plot are limited to a  certain   level; but the point about any TV series is that if it  "improves"   language, then that is certainly good for anyone.

Oui oui! Yes because I love Game of Thrones! Hahaha. The others are right in that it's not neccesarily "modern" English but I think that if it's the kind of genre you enjoy, you will learn a lot more than if you watch a "modern" show that doesn't interest you. 

Yes, I think series like Friends, How I Met Your Mother, Modern Family etc. are more beneficial when it comes to learning English, especially conversational English. Because this is how people use the language on daily basis.
