the director ruined this movie

In a 2003 magazine interview with Lisa Odham Stokes, he relayed his thoughts...

"Fred Murphy is the director of photography. He shot Mothman Prophecies, Stir of Echoes and October Sky. A very experienced and good cameraman. We talked a lot about how to make the film more interesting visually. Using more primary colors. There's the dream world, Freddy's world, and it's all reds. In one sequence where the kids get Jason drunk and he passes out, he falls into Freddy's world, his boiler room. It's more surreal. We can play with the color red, it's hot. Jason's world is all about water, because he drowned in the lake, so with the water and the waterfall, it's all green, really, really green, and steel blue for the night."

"The studio was saying, maybe we should try making this PG-13 so we have a broader audience, and I said No, that's the most dangerous thing - don't be too ambitious. People who want to see Freddy vs. Jason have to be a hardcore audience. People outside of that audience would not buy a ticket to see this unless word of mouth is good. So I said, foremost, it's my responsibility to satisfy that hardcore audience first. Then you have more respect for your work and hopefully that will translate to the other audience."

The Director obviously was more biased toward Freddy than he was Jason, which is why Jason was treated as such in the movie
