The RAF are not seen as the "Bad Guys"; the film is very fair to the British. I think the German film makers could have been more critical than they were. Instead, they show no self-pity at all; and I suspect they may have exaggerated the awfulness of the Nazi regime to their own people. They show summary executions as an almost everyday occurrence. I have no idea whether that was true or not.
I thought that the American Air Force also bombed Dresden, but this is not mentioned in the film.
The film is very compelling though just a bit too fanciful. It is not likely that a British bomber pilot and a survivor of a shooting-down could lose himself in a German hospital and begin a love affair with a German nurse. And it is not likely that an extremely valuable, totally illegal horde of drugs which was absolutely vital to the future of an important German family would be kept in a cupboard and the key left in a niche nearby.
Have noticed that continental films often feature the British. This is in stark contrast to the usual fare of war films made in the USA were the British are not mentioned or if they are, are shown trailing behind the Americans and lost in admiration for them.
This was one of the few war films that I have watched avidly from beginning to end and I was more than happy to suspend disbelief as and when necessary. Though the leading lady might have had something to do with that.
