Where's all the creativity gone?

The title of this article refers mainly to the entertainment industry which includes movies and TV. There seem to be fewer and fewer original movies and TV shows while there seem to be more and more sequels, adapted or inspired work. I'm not saying these movies and TV shows lack quality (some of them do), it's just that they begin to get monotonous. Take for example one genre of movies, comic book movies. Ever since the popularity of Spiderman, more and more comic book movies are being made ( for example, Hellboy II, Iron man, The Dark Knight, The Spirit all came out this year). Soon, they will run out of good comic book characters and we will have to watch movies about Banshee or Starfire (both are actual comic book characters). In a similar regard, American Idol kind of jumpstarted the reality talent competition genre. I also dispise the fact that more and more sequels are coming out. The Shrek movies could probably go on until infinity and still make a ton of money each time. However, that doesn't mean there should be such a large number of sequels. The only good sequels are ones in which each movie is part of a larger story like Star Wars or Lord of the Rings. I think movie and TV producers should try to be as original as possible. Just think about the future. If you keep adapting existing stuff, what will the movie and tv producers of the future adapt their stuff on?
