Well, I watched the final part and unfortunately I was not as impressed as with the previous episodes.
The questions and previous ambiguity seemed to resolve itself into a pretty one-sided impression of the Jews being a monolithically bad group.
It is not virulently anti-Semitic in the way that
Jud Suss was. That is obviously ridiculously hyperbolic. Yet there is some comparatively mild anti-semitism in there. Jewish characters who had previously been liberal, anti-Zionist or naive and apolitical such as Eliza's dad, Paul and Eliza herself suddenly become, at bottom, just like all the others. This is what I took from the fourth episode anyway.
I can certainly see how that can be found objectionable.
One example of what I thought was a bit of a heavy-handed Jews/Israelis are evil was near the end:
Most of the events probably did happen in the 1940s parts and similar actions probably happen to those depicted in modern Israel but some of the narrative was rather manipulative, I thought.
Certainly viewers don't come away with the impression that fleabeetle's uncle did. The Arabs are like the innocent and pacifist Eloi of H.G Wells'
Time Machine belatedly driven to a tragically inept if brave self-defence.
