I wouldn't recommend trying to watch it for free illegally. Sometimes, there are limited-time free trials on legitimate streaming services. You could also look for it on public libraries' digital collections if they have such offerings.
Watching it for free might not be legal or ethical. You could check if it's available on free streaming platforms with proper licensing, but be cautious as many unauthorized sources can get you in trouble.
Watching American Horror Story for free in a legal way can be tricky. Maybe you can wait for it to be shown on free-to-air TV channels or see if any friends have a subscription and can share it with you within the platform's rules.
