¿DEBERÍA VER SERIES Y PELICULAS EN VERSION ORIGINAL?
The quick answer to this is yes! I know some Spanish speakers who are quite reluctant with regards to this idea because they find it difficult but there is no doubt that it is a good strategy.
These days it is extremely easy to watch content in original version with services such as Netflix. It is clear, that countries where most TV programmes are shown in the original version, such as the Netherlands, have a higher level of English because they are used to hearing English all the time!
Hope that helps!
