This is a watchable series, yes.
However, it is sodden with woke juice from start to finish. Some lines are SO preachy woke, they made all eyes roll in our house.
This is especially true of the Indian army section and constant sniping at the British empire (you know, the one that created India). The 3 million strong volunteer Indian army of WWII was by far the biggest in history, though a few Indian supported the Japanese against Britain (BOSE).
And of course every single woman has to ne STRONGANDINDEPENDENT, because no woman in a drama these days cannot actually behave like many women so, being supported by men, crying etc. Nope, they have to be STRONGANDINDEPENDENT even leaving their babies behind to go to war. The section here where that mother picks up another baby is gruesome in its metoo virtuesignalling.
If this were DEWOKED it would be excellent. The wokery makes it mediocre.
Though some scenes and parts are really excellent. Though maybe it could be cut down and lose an episode.
I liked the Polish actors/themes and the harsh mother character has developed well, together with mysterious tenant.
So not classic, spoilt by woke, but passable. 3.5 stars rounded up
