[QUOTE=Tokarev;1172651]Amazon's Bosch is rather unique in that it seems to have stayed true to the book character while changing things enough to make him relevant to a different era. He's not a Vietnam vet for example. And the stories themselves are all adapted from the novels but with enough difference to make the shows worth watching. A different genre entirely but The Expanse is also good in this regard. /QUOTE]
The reason may be that, for both shows, the writers of the books are involved in the shows.
