Personally, I think it depends.
If you intend to brush up your speaking and listening skills, I think watching movies or dramas is a great idea. However, if your intention is to pick up and polishing English conversation, I think it will be more effective if you could engage yourself in real conversation as often as possible. By doing this, not only you can practise on the pronunciation and listening, you can condition your mind to response naturally to exchange of ideas in English. Of course, the process of internal translation, in your case, between English and Chinese, can be further strengthened and enhanced.
Hope this helps. Cheers!
