Regarding Cyprian's comments about "Ostrov", he picked out the 2 or 3 things which gave me a pang of unpleasantness.
Perceptive as always, Cyprian !
The Nazi scene was in fact so overdone, which I recognized at the time of viewing the movie. Surely the Nazis would have picked them up out of the water and kept them as prisoners.
Even sent them to join the ranks of the arbeiters, the workers they had drafted from France and all over to keep their machine going. Young French men were hauled off the streets and sent to Germany later in the war for this purpose.
This is the SOLE reason that the ranks of the COMMUNIST - based resistance to the German occupation of France, the Maquis, bloomed in that era.
Otherwise, few French would have joined the Maquis. Just mentioning that part.
Back to the film, that German battle scene was wildly improbable. However nearly all that followed was so good that I was willing to let the not-believable start of the movie go.
As Cyprian mentioned, the part about the possessed daughter of the Soviet Admiral was the other disturbing scene to me. It was painful to watch. Almost indecent when she was lolling about in the snow.
However, I figured that the point needed to be made that she was really a handful. Thus her cure by the Starets would be
the crowning scene of the movie, wrapping up all the loose ends. Don't want to give anything away for those who have not yet viewed it.
In contrast, I remember clearly the scene where father and daughter are in the train compartment headed north to the skete or monastery of the Starets. The viewer knows the characters have some significance, so waits in suspense. But what could be the relevance, he waits to find out.
