The first thing that strikes you about this documentary is it's low budget straight to VHS feel. Don't be put off, this is a well researched, balanced and well paced look at the war on the Eastern front in all its brutality.
This is not clickbate made for YouTube or Netflix, nor are there reenactments in colour or use of footage from a Hollywood film to make it more palatable for the casual viewer. The analysis from the historians and university lecturers is insightful and often based on first hand accounts from veterans they have spoken to in their studies. There is no repetition every 15 minutes for where an advert break might take place and there is extensive use of real archival footage.
Overall, a far higher quality documentary than you see most of the time in the 2020's and it's despite its low budget presentation well worth an hour of your time if the subject matter interests you.
8/10.
