I've watched the whole season
I really liked it, but it's one of those types of shows that begins with several mysteries and by the end more new questions have been raised than old ones answered, so if that frustrates you it's probably not a show for you
I think my favorite thing about it is the fact that most of the major characters have some morally grey aspects to them, yes even the SS and Kempeitai leaders
Obergruppenfuehrer John Smith is probably my favorite character
The last minute is an absolute mind fuck, and a huge cliffhanger. If it doesn't get a second season I'm gonna rage
Got the book on my shelf though so definitely gonna read that sumbitch soon
