A film had to exploit electricity as a horror element and this one is probably the first one that comes to mind in those of its genre. Shocker and The 13th Floor had a more interesting way of integrating the concept of domestic electricity into their scenario while Pulse dedicates itself to it.
The special effects are surprising. We are astonished by the metamorphosis of electric circuits in fusion and other unconventional miniature camera angles. The actors help create an easily accessible film. Sadly, having a child as a hero, it is difficult to take it seriously. The violence is very moderate except for the ending. Precisely, if the whole film had the rhythm of its last fifteen minutes, it could have provided us with an electrifying version of the excellent Final Destination.
