Movies- There are far too many to count at this rate but to name a few: Interview with a Vampire, Bram Stoker's Dracula, Phantom of the Opera, The Hunchback of Notre Dame. I think the majority of the reason for my love of these movies is they all have that dark romance and gothic appeal that I don't often see in films. For a few of these (namely two, the musical scores are exquisite.
Television: Hands down, favorite show had to have been Penny Dreadful. It was dark, it was sexy, it was romantic, cruel, and had lots of bloodshed . Of course there were classical horror icons like Frankenstein and his monster, Dracula, Hecate, the Devil, and the beautiful Dorian Grey. All the while, the setting took place in Victorian England around 1888. It was everything that I adore and then some.
This and Salem~I'm absolutely in love with anything to do with magic and the Salem witch trials. The Edwardian style costumes were absolutely stunning and the plot kept me on my toes. Not to mention Lucy Lawless (known mostly for her role as Xena the Warrior Princess), was in the show, along with Marilyn Manson and Steward Townsend.
So, the TLDR; anything with bloodshed, elements of horror, monsters, romantic gothic fashion and a musical score that could raise the dead is my bread and butter.
