I was pleasantly surprised by "Dr. Ivens' Silence;" while in one sense it has a fairly conventional or even perhaps even stereotypical science fiction idea near its heart (aliens from a more developed planet are shocked at our human propensity for things like war and income inequality), it has a very intelligent script that does some very original things with it.
Despite the science fiction premise it is, as the title suggests, first and foremost a character piece about Dr Ivens, and in that sense it is a very effective one, assisted by the fact that Sergey Bondarchuk gives an excellent performance in the leading role. His initial "silence" comes at the beginning when he says nothing about a fire that he sees on the wing of his airplane, and his final silence comes at the end when this readiness for death has been fulfilled.
The fact that its essentially an unlikely human-alien love story is novel enough to allow it to explore the themes in novel ways, and while it is detectably pro-Soviet in its depiction of this story set somewhere in Western Europe, it is at heart a rather despairing message about humanity's lack of readiness to react to the coming of these creatures without Earth's characteristic flaws.
In all, a success of cerebral rather than action-oriented Soviet science fiction, through good dialog and good characterization
