I found the series incredibly frustrating. Yes, it was cool to see the "great men" dramatized.
But the show did a horrendous job depicting military events. For example, the show repeatedly used modern US destroyers (missile turrets, modern radar, CIWs, etc.) in place of WW2 Japanese and American ships!
For some tanks, it used Russian and American models that were not produced until decades after WW2 ended!
This is the freaking history channel for goodness sake. They have more WW2 footage than probably anybody and yet they use clips of Cold War and modern vehicle and vessels in place of their WW2 versions? WTF?!??!?
