Full disclosure: I don't have cable. And because the hubs promised that we had a digital television even though we, in fact, do not, we never got one of those box things for the digital switch, so even the basic channels come in like snow. Which is kind of nice, since I live in Florida. But basically, my access to television is limited. We have Netflix, and the majority of my queue is filled with seasons of shows I've heard great things about (mostly because I can only spare 20, 40 minutes tops a day for TV, so watching movies is really out of the question). If I really love a show, I'll start watching the current episodes online, but other than that, I'll just wait for the new season to come out on DVD.
That being said, I do have to admit that my limited television watching has actually taught me quite a bit about plot devices and unique ways to tell stories. Many of my favorite shows have a unique storytelling style that I admire, and could thoroughly enjoying in a book.
make people want to re-read.
So now, thanks to HIMYM, AD, LOST, and many other shows, I've learned to take television more critically. I don't simply watch and ignore. I watch and think, "Is this a good plot device? Could I use it somehow?"
What about you? Do you ever learn anything from television (or movies - like Momento!) that help you in your writing? If so, which ones?
