You were not 'put off' by the endless, mindless fighting and conflict between the leading characters.???? It may well have happened in the situation these unfortunates found themselves in, but is it necessary to show it over and over again ???? I was looking for more information on this interesting story but ended up fast forwarding through many of the pointless, mindless violence, sequences.
I was somewhat intrigued that the Japanese should spend two days building a vital pontoon bridge across the Khalkin Gol (river) and then leave it unguarded at night ----------- allowing our first batch of prisoners to use it as an escape route !!!
It would have been a great benefit to have understood how Tatsuo, the former Japanese Imperial Army colonel and long time rival to our main hero, managed to get from 'death's door' in Dedovsk to Normandy. I can understand how our main hero, the ethnic Korean, managed to get drafted into the retreating German Army but not Tatsuo.
I would also point out that the mountain range depicted as being just out of this town, which is within daily commuting distance of Moscow (I know this personally) does not exist. There are no mountains of the type depicted within hundreds of kilometres of Moscow, even the 'mighty Urals' are, in their southern regions mere rolling hills - and hundreds of kilometres to the east of Dedovsk/Moscow. Similarly the Wehrmacht was in Dedovsk for a short period of time and the long Nazi banners draped from the remains of the office block being fiercely defended, and attacked, simply would not have been put up by desperate German fighting troops seeking to hold one of the towns vital to thrust to Moscow..
Similarly I was well put off by the beautiful flowing locks of Tatsuo when depicted as being in the German army - perhaps it was written into his contract that he would not have to suffer the traditional army close-crop. The same goes for the rather bellicose German officer commanding the construction battalion he was in - long blonde flowing locks of hair under his officers cap. I think this would have been a disciplinary offence in the Wehrmacht.
The same goes for the lack of 'scars', from the many wounds Tatsuo is depicted as suffering during his adventures, on his magnificent physique.
I read several years ago of a similar instance of an 'Asiatic' in Wehrmacht uniform being captured by Allied forces, I think again US, in northern Italy. It seems he was a simple shepherd conscripted by Red Army recruiters when he strayed across the porous border from somewhere in western China/Tibet region. He spoke no English, no German, Russian or Italian, merely 'went with the flow' ---- when his unit moved so did he, when they fought for their lives so did he.
Perhaps an interesting, more realistic, film could be made of his life and adventures.
All in all this film is not a patch on Brotherhood or that other magnificent Korean film 'Assembly'
