Slant Magazine gives it 2 1/2 out of 4 stars and says,
Pulse crafts an eerie vision of dawning techno-hell, one in which the communicative devices designed to bring people together have, instead, fostered nothing but loneliness and social alienation. It's a theme that lurks within many of J-horror's finest, and remains prevalent throughout Sorezno's supernatural thriller thanks to repeated scenes in which (consistently one-dimensional) characters either fail to successfully converse via phones or IM'ing, or falter in their endeavors to have meaningful face-to-face dialogues with those they care most about.The New York Times pans it. DVD Talk calls it "uneven" and says, "you will see nothing but superficiality in the regressive retelling". Classic Horror likes it. Rotten Tomatoes has a critics score of 10%.
