Here's the problem: horror films aren't family friendly. They're gory, they're violent, and they're vulgar. Even setting that aside, there really aren't very many "conservative" movies overall and there are almost no truly "conservative" horror flicks. Still, as a Right-Wing horror film aficionado, I can at least make a few solid recommendations that might have some extra-added appeal for conservatives. <p> Cloverfield (2007): This is probably the best "giant-monster" film ever made. The monster was well done, the scenes were creepy, and there was a certain realness and fundamental decency to the characters. This is how you'd like to think ordinary people would react in a crisis. Meanwhile, the military was in the thick of the action, bravely fighting against the Cloverfield monster and handling an impossible situation the best way they could. It was ultimately a grim movie, but once things started rolling, the film keeps you on the edge of your seat.
The Dead Zone (1983): Christopher Walken is the lead in this Stephen King story about a deranged politician and the man who was willing to sacrifice everything to try to stop him from launching a nuclear war.
The Exorcism of Emily Rose (2005): This is a cleverly written film that simultaneously treats Christian values respectfully, while leaving non-believers room to doubt. It was also inspiringly creepy enough to convince me to actually read a distressing book on exorcisms called, The Dark Sacrament: True Stories of Modern-Day Demon Possession and Exorcism.
The Exorcist (1973): This in one of the most genuinely disturbing movies that you'll ever see and it's not for the faint hearted. But, it does feature self-sacrificing priests who are fighting spiritually against true evil. That's very rare for Hollywood, where members of the clergy are habitually treated as drunkards, hypocrites, perverts, and villains.
