Most of what I would say has been said by other members in their comments.
Only thing I would add is the huge oversights in the sets. The barracks high in the Austrian alps in 1940's have metal frame windows.... possibly aluminium. I would imagine that they would have been wood frame back then.
In one scene, you can see two large propane tanks in the background. I am betting the barracks set is a summer camp, resort, or roadside motel.
In one scene, a barrack has a #2 on the door. In another scene, presumably at a cabin at a distance from the barracks, there is a #3 on the door. Again, indication of a resort or motel.
There is also in the cabin scene, what appears to be a steel-insulated door commonly used in residential construction in the modern day... the standard 6-panel design. Would a cabin in the alps have such a thing?
Effects were so incredibly weak.
Do yourself a favour, skip this one. I don't know what the producers were thinking.
