When I first picked up Mile 81 from the Kindle store I knew it was going to be short being that it was listed as a Kindle Single. I expected it and yet I was still a bit disappointed with it.
Upon completing the book my wish is that it would have been an extra 20-40 pages longer so that I could get more of a feel for it.
The mystery car, evil entity, whatever it truly was could have been fleshed out more. Has it done this before? Will it do it again? Where did it come from and where did it vanish to? There could be so much more there and who knows, maybe in the future there will be. I would definitely like to read more about it.
Also, I would have liked if the ending was a bit more drawn out. It was just sort of "Well, I have nothing else so let me try this" and blammo - it works.
I would have preferred if there was a lead up to how the car was dispatched. Maybe some sort of happening to give the hero an AH-HA moment before he took care of business.
Either way, much like most everything else Stephen King that I have read I did enjoy it, I just feel that he has a lot of other short stories that are much better than this effort.
