TV Tropes

There is a fun website called TV Tropes that dissect "tropes", or common devices for storytelling used in television (and movies, and comics, and literature). Tropes aren't necessarily clichés, but you'll find a lot of those too on the site. Once you read it you'll be looking for tropes in everything you watch, which may ruin your whole viewing experience (or make it so much more fun). You've been warned.
