I was deeply disappointed with The Long Earth. Was very much looking forward to it because liked the concept. My Discworld books get reread constantly, and same goes for Good Omens and Johnny and the Dead, but this I struggled to finish. I was very conscious of the amount of dialogue, which usually implies that there's not enough happening. The action that's there seems contrived. Joshua gets in a dangerous situation with the elves. First he tries to run away, then he tries to fight, despite the fact that he's lost his knife. Hello? He's a natural stepper, isn't he? Why wouldn't his first reaction be to step away? And the omnipotent Lobsang does nothing to help?
And would large numbers of people really move irrevocably far from civilization with it's medical benefits and the occasional ice cream? Why would you have to go hundreds of thousands of steps away to set up on virgin territory?
I'm quite happy to suspend disbelief but I get irritated by inconsistencies. Discworld has it's own rules that we readily agree to accept, but we'd get grumpy if Superman popped in for a visit.
To me, the writers had a choice. They could have explored the more mundane things that the vast majority of steppers would have done - ie set up camp on a beach in Hawaii or established vast marijuana plantations a few steps away from LA Central (all right so that's autobiographical wishful thinking). But instead they launched off on A Quest. But they weren't exactly trying to dump the ring in Mt Doom, were they?
I'm sure this will offend the vast majority of TP fans/fanatics, and maybe I had my expectations set too high, but IMHO this book would sink without trace if it had come from anyone else.
