Shudder offers no-frills access to pure horror cinema, which it both licenses from other studios and produces in-house (notable originals include When Evil Lurks and Perpetrator). The streaming service is easy to use and isn’t cluttered with ads, plus it makes sure to add a new title every week and curates its selections without the help of an algorithm. Plans start at $6/month, which you can try with a 7-day free trial.
