Konami was trying to keep the dirty truth a secret, but it didn't do a good enough job. Through the power of JOURNALISM, user Giromancy from the Silent Hill Heaven forums has acquired photographic evidence proving beyond any shadow of a doubt that the original Silent Hill is a remake of the Arnold Schwarzenegger classic Kindergarten Cop.
It makes sense that an undercurrent of sexuality runs throughout the Silent Hill series. Kinergarten Cop was the movie that taught the world that "boys have a penis, girls have a vagina" and questioned who is your "daddy" and what does he "do." Those themes clearly carried over into the game.
