Hey so just curious if theres anything that has a 24/7 horror movie channels so its almost like watching tv just with random horror movies playing?
Well if you want to spend 30 bucks AMC Plus has a deal, I think until May 26, 29.99 for an annual ad free subscription which includes Shudder. It dose have “live” TV channel but not a lot of them, 7 or so, but Shudder TV is one of them so all horror all the time.
Most of the FAST apps have horror offerings and “live” channels, mullvad DNSSEC DNS server works to block ads on Tubi (has a couple live horror channels). Pluto TV but Pluto has a great horror live TV section but ads.I don’t really watch All the FAST channels but I’m sure the ones that include live TV do have one or two.
Of course most of the “other” App that get mentioned on this site can be useful if you know what you want to watch. But not necessarily live TV.
Not sure if that is useful to you, some here won’t pay for anything except Debrid. (Just a little sarcastic humor, simmer down 
)
If you got yourself a subscription to any of the IPTV services that are discussed here, there are some 24/7 horror channels as well as thousands of other channels plus on demand TV and movies. It’s a lot of bang for the buck.
You can try Shudder from AMC. All horror movies and shows on sale now.
