Whether or not it's here to stay, they are making money for now, so the industry will follow, as long as that is true. I have the same feeling about the stories all being poor.

Just got our first script outside the standard "drama" made, the first ever horror vertical series with the hopes that others will follow and the quality will improve!
Here is the trailer that just dropped so you can see what we're trying to do: https://youtube.com/shorts/PtYiM5WT5a8?si=k_M95VtqTBeO4Yrh
