Elvis: I guess we’ll just have to “agree to disagree” on this one. Glowing red eyes just do not scare me as much as a well-rendered werewolf (unless, of course, I’ve already been shown the werewolf earlier in the film, and can therefore picture what the glowing eyes represent).
In the two versions you describe, each with the same buildup, suspense, and denoument, give me the one that actually shows the monster every time, assuming the monster is well rendered. If it’s a crappy-looking monster, however, I agree that showing only the eyes would be much scarier.
I guess where we really differ in opinion is that I think that filmmakers actually can produce a monster that is every bit (if not more) scary as I can imagine on my own, whereas you are convinced that your imagination is far superior to anything that could be shown to you. I certainly can’t dispute your powers of imagination. Again, though, I’m very glad that mine are not so well developed. When I hear a noise in the middle of the night, my first thought is, “Stupid cat!” and not “Oh no – it’s some hideous and nameless monster the likes of which I’ve never seen before and that is far scarier than anything I could ever see in real life!”
I wonder, though, whether this whole “what I can imagine is scarier than anything I’ve seen or could be shown” thing applies to emotions other than fear? If, for example, you get hungry and start thinking about what you want for dinner, do you think about a particularly good dinner you’ve had in the past or a specific food, or do you instead find yourself imagining some wonderful, incredibly tasty food that is 100 time better than anything a chef could ever prepare for you in real life? Or (and I apologize for getting crude), if you are the sort prone to sexual fantasies, do you fantasize about real people you either know or have seen (in movies, magazines, etc.), or do you instead fantasize about idealized, imaginary women 100 times sexier than any woman you have ever seen before or could ever possibly be shown?
Personally, I hunger for food I’ve tasted before, fantasize about women I’ve seen before, and have nightmares about monsters I’ve actually been shown. I also imagine driving very specific sports cars, for that matter, and not fantasy vehicles made out of whole cloth.
Again, though, that’s just me.
