I once wanted to use American TV shows to help me learn English, but I found it is too hard and not very effective. A lot of TV shows contain many spoken English words or terminologies which I have never heard before and maybe will not hear again. It also requires an American or a werstern culture background to understand some lines or stories.
Now I can watch some TV shows like Devious Maids without subtitles, which is relatively simple for me, but for comedies like 2 Broke Girls and The Big Bang Theory, or law shows like The Good Wife, it is impossible for me to understand these shows without subtitles. Even for Devious Maids I can only understand 90 percent of each episode.
My conclusion: choose family dramas which contain many words that you can use in your daily life and are easier to understand.
For Chinese studying, I won't recommand 《西游记》. Not only because it is a very old show, but also because it uses a lot of "anticent style" Chinese. Normal Chinese people don't talk like roles in this show do. But I agree it is a very good show. You can watch it for entertaining.
