Top five gothic films or top five gothic novels?

Alright, here's both:

Top ten gothic novels (in no particular order of merit, sorry I can't do just five):

Jane Eyre

The Woman in Black

The Hound of the Baskervilles

Wuthering Heights

Dracula

Frankenstein

The Picture of Dorian Gray

The Silent Companions

The Thirteenth Tale

The Shadow of the Wind

See, now I've left out Daphne Du Maurier... Oh well, I can sort-of cheat by putting her in my top ten gothic films (again, I can't just do five, and in no particular order of merit, just off the top of my head):

Rebecca (1940)

Les Diaboliques (1955)

The Haunting (1963)

The Innocents (1961)

The Name of the Rose (1987)

Angel Heart (1987)

Suspiria (1977)

Nosferatu (1922)

Coma (1978)

The Orphanage (2007)

A bonus: Nightwatch (1994). Don't confuse it with the 1997 Hollywood remake. You want the 1994 Danish version. :)
