Be a little selective in your viewing choices. Pick stuff that you would normally enjoy. Remember that films and TV shows can contain very mumbly dialogue, as I said earlier. And even just kind of grunting during long fight scenes. Try to pick films that are pretty simple and perhaps comedies that focus on the dialogue, rather than visual storytelling. Some content is in a certain kind of register that might not be applicable to the English you need to use style of language documentaries.
