I think the games could have their moments, like the room with the disjointed "Twinkle Twinkle Little Star," and the more subtle "Make us whole" bits, but a persistent tension didn't really last for me. Partly because Isaac's a walking arsenal before too long, and partly because the jump out of vent attacks really only startled me the first few times.
I'd say this about sums things up. Dead Space is just doing what all Survival-Horror games try to do: build up atmosphere. Being alone in the dark corridors of a spaceship or space station, seeing various walls covered in blood, hearing various strange ambient sounds, etc. It's all trying to give you that "hair standing on the back of your neck" feel that SOMETHING'S about to happen. This is meant to be the set-up for the "pop out of the vents" jump-scare that every monster in those games uses.
The problem is, once you've played the game for 30 minutes and you realize that the monsters will ALWAYS come out of the vents (or be just laying on the ground in such a way that just screams "yeah, they're not really dead"), the jump scare doesn't work no matter how much atmosphere and setup they put into it. You walk into a new room, see like 5 of those special vent covers and just face-palm, thinking "Well this room is about to get messy." You take a couple steps in and sure enough your prediction comes true.
The point of a jump-scare is that the target doesn't see it coming. If you use the same jump-scare device (in this case the vents) then the jump-scares won't be nearly as startling to the target since they'll be fully expecting it.
That said, I still enjoyed both the games, prefering to use absolutely nothing but the standard-issue plasma cutter since all the other weapons make the games way too easy. I thought going through the Scientology Unitology church in DS2 was pretty creepy what with all the people laying around dead with bags over their heads, showing that they all performed some cult ritualistic mass-suicide. All in all I'd say they were decent games, but I wouldn't really call them scary.
