Well, there are anthologies like Trick r Treat, Creepshow, Tales from the Crypt, V/H/S and the ABCs of Death that you might enjoy. Those aren’t shorts, per se, but if you like shorter-form stuff, check them out.
As for true horror shorts, one of my favorites is The Cat With Hands. It’s creepy and cool and pretty and spooky all at once. There are a few great horror channels on youtube, like Daywalt, that are doing horror shorts frequently. Below is a big list of more. I’m going to include links to the shorts you mentioned, for anyone who hasn’t yet seen them.
It’s an article from the creator of Sons of Anarchy on why copyright is important. I can’t say enough - if you want great movies, music and art then you need to BUY it! Illegally downloading music and movies hurts the artists trying to make us all great content. I don’t want to see more shitty reality tv because it’s cheap to produce. I want great shows like Sons of Anarchy and the Walking Dead. I want amazing horror movies that have the budget to realize their terrifying vision. I want amazing music, not recycled pop.
If you love art, please reblog this and spread the word.
"Every writer, producer, actor, musician, director, tech wizard, and fine artist working today needs to be aware of what this all means for our future—we will lose the ability to protect and profit from our own work. Every kid out there who aspires to be an actor or musician or artist: This is your future that’s at stake. More importantly, everyone who enjoys quality entertainment: This impacts you most of all. Content excellence cannot sustain itself if it loses its capacity to reward the talent that creates it. Consider this clunky analogy: If your local car dealership started selling your favorite luxury car for $1,000, then $100, then started giving it away, what do you think would happen to the quality of that vehicle? Before long, the manufacturer would be forced to let go of the skilled laborer, the artisan, and the craftsman, and eventually cut back on everything in the production process. And before long, that fabulous, high-end car you so enjoyed will be a sheet of warped plywood on top of two rusty cans." - Kurt Sutter, creator of Sons of Anarchy
