I am relieved to see several folks with similar opinions on HDM -- I was worried that my vision was clouded by sour grapes. See, I've been kicking around ideas on using intelligent sub-atomic particles as a basis for a story for years now, and I had only recovered from the shock of seeing Michael Crichton's sheissburger about nano-critters that eat people when I saw the Golden Compass trailer. Cracking the book and seeing that it revolved around Dust nearly sent me through the roof.
My 11-year-old has been bringing home Madeline L'Engle books lately, and I thought Amber Spyglass felt like it could have been one of her books; I liked the ideas, but they were tossed together in a stilted way, and kind of shuffled to a rambling ending that was as difficult to care about and reach as the end of this sentence.
I guess the tough question would be, how to fix a boring fight with God? Here's what I was expecting (skip to avoid near-spoilers):
(scene: atop a mountain, many lightning bolts)
God: I brought you into this world, and I'll take you out!
Girl with inexplicable powers: You've been in charge too long, and are drunk with power.
Boy with big, glowing knife: I will use my inexplicable skill with this device no one understands to unseem you from the nave to the chaps.
God: Zap! Ha, now you are dead.
Girl: No! My first knee-weakening crush is dead! My free will is back! (stabs God in groin with subtle knife)
God: Ow! I am undone, Horatio! (blinks out of existence, taking everything with Him)
Girl's atom, floating it nothingness: Are you alright?
Boy's atom, likewise: I think I lost an electron.
Girl's atom: Are you sure?
Boy's atom: I'm positive.
