Okay, I was able to rent Pulse 2 from Blockbuster. I was expecting something like a Sci-Fi movie of the week film with stiff acting, tacky CG and weak story. That's not what I got. I would like in more specific terms what people didn't like about this movie?
Overall the production was fine. I think they pulled off the "apocalyptic" tone much better than in the first. The tone of impending doom was one of the trademarks of the Japanese original. I also listened to the commentary which was interesting as they used a lot of green screen to cut production costs. That even meant that some of the house and apartment scenes were green screen with multiple composites.
What I suspect here is that people just don't like the anti-technology (especially cell phone) message in the film. The director/writer says they weren't necessarily going for that but it comes off that way. According to the commentary Pulse 3 concludes the trilogy as the guy in the red outfit at the beginning figures in more. Pulse 3 is scheduled to release next Tuesday on DVD.
