Of the 3 I read, this was the least entertaining, I think the stories are wearing down to mere money making. It's like the Final Destination movies, it just keeps going.
This was interesting enough but certainly for juvenile, sadistic children. I mean why do things like this exist? Well, I give it one thing, these are fun stories, and slightly if not very disturbing. If Stephen King had his way with these, a whole new generation could be insomniatic.
I still enjoyed it, but the sub plot was cheesy and unoriginal. Just weird really.
