I voted Reservoir Dogs, just because of how raw that movie is. Real intense. Pink vs White, White comforting Orange, Mexican standoff.
Thinking about it, Pulp Fiction did introduce me to one of my favorite movie characters ever (Winston the Wolf). But I guess I just don't like how it's structured, several short stories as opposed to a single whole story. That's just my personal preference tho.
But I do completely understand the genius of those stories. Those would be the type of underground (pulp) stories (fiction) that criminals share with each other, starting with the phrase "You won't believe the type of crazy shyt that happened to me this weekend.....". Honestly tho, I would prefer if this movie was just about Travolta and Samuel L Jackson.
