You know, something I've noticed about King, and people who like King, is that he is super hit or miss even to the people that like him. Don't know why you're being downvoted for sharing an honest opinion. If you tell me your favorite King book I'll read it if I haven't already.

I think a lot of what I liked about this one is the concept of time itself being obstinate and resistant to change, and that changing something big might cause the universe to come flying apart at the seams. In most time travel you find people trying not to change anything because even the smallest change might have unforeseen consequences for the future. In this one, time itself is the monster, and this faceless, unknowable monster hates change. It'll screw up your whole entire day if you screw around too much.

I also liked the approach to time travel taken, here. No mad doctors, no fancy science, just an inexplicably weird thing. How does it work? It just does. Why? Fuckall if I know.
