Britton, who explained that she took on the role because it was "the polar opposite" of her part in Friday Night Lights, admitted that she is not a big fan of horror.
"But I like the [American Horror Story] pilot," she told New York Magazine. "I just thought it was beautifully wrought.
"There are parts of it I'm not in, obviously, that when I watch it's like, 'Oh my God, this is horrible'. But I do think that it's done with such an artistry that that's what I really love about it. For me, it transcends your typical slasher movie."
Britton confessed that she is expecting a mixed reaction to the show, saying: "I think that this is something that's either going to appeal or not appeal to people.
"I just have to say for me, not being a horror fan, I like the artistry of it. I like the character aspect of it a lot. But if I were just a regular person, not in it, I don't know how I would feel about that. I don't know if I'd just be totally freaked out by it."
She continued: "For me, this is different from the kind of Friday the 13ths of the world. This is more The Shining or the Rosemary's Baby of the world, which I've always been able to appreciate, even though I can only watch them with a big crowd of people around me and a blanket covering my eyes half the time. I feel like that's what this is. But listen, I'm not going to lie to you - it's going to get brutal."
American Horror Story airs on Wednesdays at 10pm on FX. The show will also air in the UK later this year.
