I am a big fan of the books (read all of them multiple times) and for that reason, I had trouble warming up to season 1 of Reacher because of the changes from the book.
All that being said, I could not even finish this book.
As other reviews have said, Reacher seems to be a minor character in his own book. I had to stop this reading this one and moved on to the Hunt for Reacher release as I just could not stand to see what was being done to much-loved character.
