Oh I had no idea this topic existed ! It's great to have a place to practice our English, even if it's only written (we should organize "madz English night" everywhere in France
.)
As for the subject, I'm what my parents call, a series-addict. Everytime their friends'kids are looking for a show to watch, they call me. So I often have to answer to questions like "why do you like it so much ? Why isn't it like movies ?" and stuff, and I finally came up with that theory which is that I think our generation is not pleased with "one-shot". I mean, we like books, movies, series, but the one we really like are the one we follow. It's not just TV. My favourite books are the one that I grew up with. Not like "I was a kid it was great" but like "It was there for a very long time". Harry Potter worked pretty well because every year we wanted to know what was going to happen. And they understood that, because now, the best-sellers books are series. Same for movies. They know they can't just make a good movie. They have to make more, because we have to know what comes next. See, now we even have movies that tell us what happened before the actual first movie. (I'm talking here about people who are not into the cinema industry. The one who only go to the theaters bacause they know the story or the main actor, not the one who follow a realisator or who go to the movies for the beauty of the photography) And the fact that more and more "books-series" are made into movie, also shows that we care a lot about the characters and universes, and that we look for every occasion to meet them again, even if it's the same stories, at least it's them.
Maybe the series are the first media that started this, but now you can't just say "kids only like dumb TV shows", because in the end, it has nothing to do with TV. Every media is touched by this serie-trend.
That was the 3:52PM theory, I'm going back to my Walking Dead episod, I'm late.
