Hello Diego662,
We are the Institute of Native Linguistics. In our opinion we think that you have come across a very common question. Should we watch English tv shows or movies with your native language subtitles helping you understand the context of the show? or should we just only be using our English subtitles when watching.
The obvious option is to choose the second viewing option. I would like for you to ask yourself this. Why am I watching this show in English in the first place? Your answer will probably be, because you want to learn English, right? Well, there you go! Use the tv series as a challenge to help your vocabulary grow and try not to focus too much on understanding every bit of the context. The more you watch and the more you practice, the better you will become at the language.
Thank you,
Institute of Native Linguistics
