Entertainment Weekly picks the 30 best classic horror movies, from early essentials like 'Frankenstein' to timeless chillers like 'Rosemary's Baby.'

From favorites like 'Scream,' 'Silence of the Lambs' and 'The Sixth Sense' to underseen gems, these are the 16 best horror movies of the decade.

Nell Campbell, who played Columbia in the film, remembered Bray Studios as "the most low-brow studio" and "incredibly impoverished" but is still proud of the role the film has played. "When the [stage] show opened it was 1973, only six years after homosexuality had been legalised in the United Kingdom," she said.

Horror movies can keep things scary while going to complex territory narratively, as classics like The Exorcist and A Nightmare on Elm Street show.

It's that simple, but hopefully it won't be that easy.
