I'm not going to burn down your house or poison your dog or anything like that. But I am still going to ruin your life.
I work for The Man on the 9-5 grind. I'm parked in front of a computer for almost the entirety of that time. So, while I'm doing my work, I'm also surfing the web.
One website I frequent is called tvtropes.org.
TV Tropes will ruin your life in the best possible way.
It's a website dedicated to analyzing works of fiction and cataloging the tools used to tell a story.
The amount of works they cover is nothing short of extensive. Movies, plays, books, video games, web comics, TV (obviously)- any medium that tells a story is included.
Any movie or TV show you've ever seen is probably on this site. One of my favorite things to do after finishing a movie/TV/book is to check out its tropes page.
I get insight on the story that I never would have gotten with a single viewing. They delve deep into the nuances of character and plot.
Like that other wiki, TV Tropes is patrolled by a bunch of nerds. However, it's written in an extremely casual way, making things accessible for all readers. This accessibility makes it very, very easy to fall into a hole where the laws of time and space don't apply, where hours fly by like seconds.
It also helps that there are on average a hundred links to click on each page. The majority of these links are tropes. Here are some of my favorites:
Obviously, this is an extremely small sample of the hundreds of tropes detailed on this site. They're useful to know and will change your perspective on how a story is told.
If you're a writer or interested in fiction, tvtropes.org is the place to be.
Check it out if you've got several hours to spare.
