I was going to just link to Moviehole's original article on this story, but I liked the opening line of BD's post on it so much that I'm just going to share that:
Indeed. Poor Kristen Bell, stuck in that DOA stinker. But the news here is that Jamie Bamber - Apollo of Battlestar Galactica and whose ass I recently waxed poetic upon - has landed the lead role in the 2nd and 3rd Pulse films. Yes, 2nd and 3rd. Because this story's crying out for the epic treatment.
Don't get me wrong, I enjoyed the original Kairo, but what made it interesting - besides having possibly the only scary seen-onscreen ghosts I can recall - was that it actually went all the way and, ya know, ended the world. Perhaps it's a lack of imagination on my part, but once we've seen the ghosts eat the entire world, I just don't think your story has anywhere to go from there.
Course, the only thing it'll take to change my tune and have me pimping these flicks like a maniac will be word of Jamie Bamber taking off his clothes, so perhaps the writer and director ought to think that through and write in several gratuitous shower scenes. Maybe the ghosts eat off all his clothes, and all the clothes in the world, and he's loincloth'd the entire time. I could stand behind those films being made without an ounce of shame in my heart.
