I love anti-hero type films. I love horror films. My favorite are one's that make you question your own morality. Films that make you think and challenge your audience. I also like black comedies like Bad Santa and Fear and Loathing in Las Vegas. My favorite films, however, are:
Natural Born Killers (Oliver Stone)
The Devil's Rejects (Rob Zombie)
A Clockwork Orange (Stanley Kubrick)
Taxi Driver (Marin Scorsese)
and Freaks (Todd Browning)
Very dark, cynical, and highly entertaining films.
I also love art house films like Eraser Head, Susperia, The Lords of Salem
And just about any horror film I can appreciate, especially 70s exploitation like Last House on the Left, Texas Chainsaw, and I Spit On Your Grave
I absolutely LOVE Kubrick and think The Shining was one of the greatest horror films ever made. As far as new directors, I'm loving Eli Roth and Rob Zombie
also, I can't not mention one of the greatest directors of all time, Quentin Tarantino. I've loved all his work. My favorites being "Inglorious Basterds", "Kill Bill 1 & 2), "Death Proof", and "Django Unchained".
