Yes you can watch a series in original language .....

One of my English students told me yesterday that the first American series he started watching without subtitles was Friends. It's one of the easier series to follow for learners of English, yes there will be scenes that you don't understand, but give it a go, and you'll be surprised at how much you can actually follow. The language isn't so complicated and you'll be able to understand a lot from the acting. It's a way to improve your 'real' English (i.e. not text book stuff) and it's relaxing and funny too. I can guarantee you'll feel proud of yourself when you get to the end of the episode!
