Very biased and over-glorification of America. Left out most of the important battle discussions and just ignored Russia's important and crucial role in breaking Germany. They are making to show POV from all the participated countries but in-fact they are only showing a POV where allies and America stands out great, which for a non-enthusiast in WW2 history is not very correct information providing. I think it is more of a propaganda series to glorify America. There were many battles in Europe and in Pacific in WW2 where Germany and Japan has battered Americans and its allies in battles, for example - the first naval battle of Savo Island, part of the Guadalcanal campaign and Malay/Singapore campaign by Japan.
