Query: tedious and with little drive

The latest trend in horror is to address an old idea: the struggle of characters against and unidentifiable force that will always have power over them. There is a nice tension available in these kinds of works, that of anxious rage against insurmountable powers. But when does that tension just become a bland montage of vague threats that leave the lack of resolution disappointing rather than empathic? Pulse falls in the disappointing category--there are nice overtones of the problem with an overly technical world, but these are highly unrealized, and the movie seems to prefer pulling away from any kind of empathy rather than truly trying to scare the s*** out of the audience by letting them in just enough to really fear what they don't know.
