I enjoyed the book. it's easy to criticize the author and the SEALs involved; however, when you understand what they faced and what they withstood -- I'm willing to cut them a lot of slack. And, while the book may "lack critical thinking," it does make you think.
There have been more recent articles, etc. about the event -- some saying, for example, that the goatherds were mere setups. The Taliban already knew the SEALs were there and, regardless of whether the goatherds had been killed, the SEALs were doomed for other reasons from the moment they landed.
As with most military missions that go awry, there are lots of second-guessers, armchair pundits and the like. Some of them make fair points, some don't. But, if you're interested in military history, it's worth reading about the incident.
