So for my money, the very very best medium for experiencing horror is the graphic novel. The issue, for me at least is pace, I love me some horror movies, but there have been far to many times that the pace goes to fast, or to slow, and that ends up killing the tension. Reading lets one set their own pace, but without imagery, again a lot of the tension is lost, so, graphic novels should be, and in my estimation are, an ideal solution.
But Manga stands heads and shoulders above American graphic novels when it comes to horror.
I'm aware that this might be something of a cultural issue, as we always find things that are foreign to us to be for frighting than the familiar (Ringu being much more scary than the ring for instance), but I honest think that horror manga, especially of the last 5 or 6 years, have been on the top of the game.
For me it's the perfect blind of creepy imagery, matched with spooky characters, and most importantly, frightening circumstances, which is where many American plots fail. But it's also the little things: I'm reminded, in the First Higarashi arc, of a rather Climatic scene, that had me turning pages quickly to see what would happen, but when it should have resolved, I was met with two completely black pages. I was weireded out and felt unsettled right away, it was perfect!
But what do you guys think? What makes a good horror, how do you feel about Horror manga?
