I believe literary work comes in many shapes and sizes. From comic books to poetry to novels to TV shows to video games to folk and electronic music, I believe literary qualities transcend any one medium or genre.
Some of the literary devices I look for are cleverness, humor, unique forms of storytelling, irony, fantasy, sci fi, futurism, mythology, cultural critique, social justice, poetic attention to detail, deeply contradictory characters, psychological verisimilitude, and community-building. In a broader way, though: I seek media that equip me for living a better life, to butcher a quote by this guy. My favorite stories are thus ones that inspire me to be a better person, and include the following.
American Horror Story
Crouching Tiger, Hidden Dragon
Firefly/Serenity (really anything by Joss Whedon)
Ghost in the Shell
Spring, Summer, Fall, Winter… and Spring
Terminator: The Sarah Connor Chronicles
