I was surprised as I watched this German documentary, "The Unknown Soldier", as I had no idea that so many STILL in this nation are denying, minimizing and quibbling over details of the holocaust. But it seems that an exhibit in a Munich museum about the holocaust resulted in an uproar because it featured photos, film and accounts of German soldiers, NOT just SS but normal enlisted men, participating in atrocities. Here in the States few would be surprised in the least to imagine that the German army were willing participants in the holocaust but apparently the German people (which included a lot of skinheads and war vets) were appalled as they insisted that the German army was blameless and honorable. Interestingly, these same folks refused to enter the exhibit themselves to see this evidence.
I liked watching this portion of the film--it was informative and eye-opening. However, the rest didn't seem as necessary--at least for audiences outside Germany. The rest of the film consisted of showing evidence of these army atrocities--necessary for German viewers but less necessary in countries where the holocaust is talked about more openly and which didn't perpetrate these crimes. So, in an unusual move, I'd rate the film differently depending where you'd live. In nations involved in these horrors, such as Germany, Austria and the Ukraine (where the locals seemed to gladly assist in rounding up and murdering Jews), I see it as a must-see film. As for elsewhere, it's still worth seeing but not nearly to the same extent--it's just that the populaces elsewhere don't need convincing of the atrocities of the Nazis and their friends.
By the way, although it's never mentioned in the film, I was shocked in a visit to Austria. Their involvement in the holocaust sure seemed to be conveniently forgotten. Remember that neat cemetery at the end of the film "The Sound of Music"? Well, although you couldn't see it in the movie, there is a very prominent and disgusting monument STILL there to the Waffen SS--the folks who ran the death camps!! And, in this same town there's a military museum that amazingly glosses over the holocaust amidst its exhibits on WWII. Crazy.
