Movie or tv show based on literature…

How often do you watch a movie or tv show that is based on some form of literature? If you don’t watch them, then may I ask why? Which do you prefer….a movie or a tv show based on your favorite books?

To me, it depends on the book. I thought the Harry Potter series did well being made into movies. A long series like that (7 books total) would have been more difficult to make as a tv show. It would have dragged on for years, a lot longer than it took to make the movies. However, they took one of my favorite books from Joe Hill (it was a stand alone book) and made it into a tv show earlier this year. I watched it and I thought they did a good job with it. They can continue it and make a second season out of it (it definitely wasn’t finished by the end of the first season). I would watched it if they continued it.

What about you? Do you prefer to see your favorite books turned into a movie or a tv show? Which would you rather see? Why do you prefer that over the other?
