Horror TV ID
Hey, i would like to know why you didn't put the genre "Horror" for shows ?

The list of genres was resolved a long time ago.
Perhaps here in this long discussion you will find some explanation for why TV does not have the Horror genre, as well as countless other genres suggested by users.

It block me on my website for looking for a lot of horror show.
Can you do something or is there another way to find horror shows?
Thanks for your answer !

Perhaps users have already added a Horror Keyword in the majority that deserves it.

Searching the WEB interface we have a list.
Try using the keyword Horror and its countless variations.
