By now, we're all familiar with the arguments both for and against remaking classic horror films, or even not-so-classic ones. There are certain titles within the horror community that are considered more sacred than others, though, and approaching a remake of one of these titles, there will naturally be a more pronounced sense of hesitation for fans.
"A Nightmare On Elm Street" was the film that helped establish New Line as a real contender in the independent world. When it was released, they didn't have any major marketing muscle to help them. They had to rely on some freaky TV spots and word of mouth, and sure enough, it worked. Not only did it create a new horror icon in the shape of Freddy Krueger, but it also spawned something like 11,000 sequels. That's an approximate number, but it was certainly enough of them to dilute him almost completely as a figure of fear.
The problem was twofold. First, there was little reason for Freddy's return, which makes him automatically less frightening. Random horror that just strikes for no real reason is less interesting than horror that is specifically targeting you as a victim, or (even worse) horror that you have brought on yourself. Second, Freddy started to get too damn funny. I hate wise-cracking Freddy. This is a guy who was murdered by a group of parents because of what he did to their children. This is a vile, repulsive human being whose evil was so strong that he he came back from beyond the grave to keep hurting his victims. And yet, by the time the series was done, Freddy was a Halloween costume for children, a joke. Defanged to such a degree that it was hard to remember a time when he was genuinely scary.
