Really good. Just because there are a few extremely minor inaccuracies (as there were in Band of brothers) and some cgi which is noticeable at times but still really good (fair enough considering there are practically zero planes of the era still flying) does not mean this is a bad show at all. This is one of the greatest war series that I have seen. It really does a great service to all the people who served in the USAAF and bomber command. It does a great job of conveying the stress and fear of flying in a b17. The acting and music are fantastic.
