Well Most of the time, I find myself agreeing with Jim here, but im not sure that's the case today. It seems he's kicking some hornet's nest without any reason (Although DAMN I laughed with Scare FOE).....
Evidently there is room for jump scares in horror, I dont think anyone can deny that, but I find it is a lot easier to pull off an effective jump scare. A simple Gif image can give you an effective jump scare:
(stare into this spot and you will see the point change color........ BLAM!).
Of course it requires work as well but it can be done very methodically through Action -> prolonged silence/pause -> Frantic action, and it works just fine.
I pesonally don't care much about the scare itself, but MUCH MORE about the long lasting unsettling feeling. And this is why, when playing Dead Space, the same jump scares that were effective initially, grew tiresome the further I got invested into Isaac's story. And this is also why a game like Doom 3 for me holds little interest (and i'm not being smug as to say, its artistically inferior or whatnot as Jim implies), I'm just noticing that it relies too much on that temporary high that repeats itself with slight variations, but it doesn't really get me invested or give me an insight on fear.
This in general, is why when I watch straight up horror movies, I don't particularly enjoy them, since they generally strive to you disturbing Imagery, but often dwell on very generic stylistic clichès and can rarely take that seriously. On the other hand, suspense thrillers (although genres often blend and blur) generally focus on giving you frightening IDEA, with or without the media shock, and directs our thought towards what scares us individually. The difference is that this profound fear requires to be constructed diligently, while a jump scare can be effectively created in a single scene.
So yeah, they are not the same, and in my opinion, one takes much more work to pull off psichologic long lasting fear efectively than a jump scare. And there is nothing wrong with that, noone is up in arms about it either...just different resources.
