I think watching movie in english is benefit for me because of it make me to practice language skill. Certainly it have some word that I can't translate and that make me trying to do research those words from dictionary in order to view the movie continue . I think another benefit of watching movies in English is make me hear a natural voice of actors which is the charm of movies more than a soundtrack Thailand. The disadvantage is some of the idioms is a rude words. However I think watching movies in English is advantage rather than disadvantage.
