To me it's not so much that the movies are slow-paced as much as they are about spending time building a relationship between the audience and the characters. If you don't spend an adequate amount of time doing this, then how can you expect to scare anyone?
Ti WestIn a traditional Western there's always the bravado, and it's almost like they're winking that they know they're in a Western - "Look how good I can spin my gun." In real life, when the bad guy kills somebody, or they're bad guy friend gets killed, they're upset, too, which is not typical in Westerns.
