The events of Pulse 2:Afterlife happens right after the events in the first film. The ghosts end up invading and are claiming lives like you wouldn't imagine. Survivors take shelter in remote parts of the country where wireless communication signals cannot reach. Our hero travels to a ghost-infested city to see if his daughter is still alive. He finds her but gets more than he bargains for. That's where the story begins.
Like the first movie, I didn't find too much bad about the sequel. It kept my interest til the end but, sadly, this movie was uninspired and fell flat on delivering the thrill and chills that a Japanese horror film story would. The look of the ghosts was horrible(just grease paint and actors trying to look scary), nothing like the first film. In this film, they are flickering tv images. No spooky looking ghosts here, folks. I thought we'd get treated to some good special features, at least, but all we get are commentary, two deleted scenes and a quick look at Pulse 3. After this movie, I'm not so sure I'll be returning for the third installment. We'll wait and see.
The only thing I can suggest is you rent this one. To buy? well- if it's cheap in a bargain bin somewhere....but I wouldn't pay full price for this. While it was a decent for a low budget movie, it didn't WOW me like the first one did.
