Like the other reviewers, I have found this to be the weakest so far of the Jack Reacher thrillers. Taking that into account though, I don't think it should be dismissed outright.
The structure is almost like a classic western - stranger enters a dustbowl town, helps damsel in distress, rights a few wrongs then leaves - and I think it is this familiarity which causes most of the "seen it before" type comments below.
But this is still a Lee Child thriller, and despite a very (VERY) slow start - in fact, I would say at least 2/3 of the book are behind us before it really hits its top gear - the run-in is as thrilling and exciting as you would expect.
Worth a read, but not as a first Jack Reacher novel - try Killing Floor first.
