Why it is important to see films in original version?

hello my name is esther and a few days ago in English class we watched a video that said that children spain never see movies in original version if not subtitled.  

One of the most important things in other Countries Was that put the TV in original version with subtitles in his Idoma.y why children have interest in learning to read in order to see the TV 

My personal opinion is yes, I think That is important to see films in Original version because that way we get used to hearing the language and has better pronounce. and, know how are the voices of the actors and  actresses.
