Channel Zero
The premise: A horror anthology series based on popular creepypastas, each season is self-contained as its own story.
If you aren’t familiar with the concept of a creepypasta, 1. which internet have you been using for the last decade? and 2. look that shit up, because you’re missing out if you don’t. Channel Zero may not have the highest production quality, but it does demonstrate Syfy’s marked improvement in the storytelling department since it started (remember Black Scorpion? Of course you don’t).
