I think that I have never finished a serie. I know that today is getting easier to watch series and Tv shows thanks to the internet. I think that I don't see Tv shows anymore but I am addicted to series and I never finish them because I always get bored. In addition, there are a lot of them that I had really enjoyed like Twin Peaks, it is really old, but I think it is the longest serie that I have seen. It was released on 1990 and ended on 1991. I like it because it starts really "normal" a girl was found dead in a small town in the United States, but as the episodes goes on it gets really surrealist. Besides, there is a lot of characters and each one has an unique personality. The main story was created by David Lynch, he is very famous filmmaker, but he has directed a few episodes the other were directed by Mark Frost. But even if it was on Tv until 1991, on 2017 David Lynch directed an entire third season on Netflix. I haven't finished this season....
