Does anybody really care what anyone else thinks? I'm not sure that Google reviews serve the process of debate and critical appraisal of anything in a way that contributes to a sense of wider understanding. More likely, they probably moredirectly assist in the process of creating improved algorithmic data about those who read and write them. In any case...
It seems to me that the book(s), which the series is 'based upon', has four major, core qualities:
1 A propensity for excellent dialogue. In fact, most of the book(s) is based on these excellent exchanges.
2 The presentation of the idea of circular processes of establishment of empire, growth of empire, stagnation through over expansion and eventual disintegration; not an uncommonly observed historical assumption.
3 The proposal that there can be objective oversight via science (maths, and in this case 'psychohistory') which is predictive if applied to mass human behaviour; read 'dataism' and algorithms. This objective oversight is contrasted with myth and ritual throughout, myth which is nevertheless utilised to coax the 'less informed' into following a cohesive historical plan aimed at restoring order; read pacification to intended order via religion. (Those who put out the peoples eyes condemn them of their blindness.)
4 Those with 'vision' - the overseers - are elite technocrats who seem to have, somewhat benevolently, a concern with establishing and maintaining order and diminishing the effects of the inevitable cyclical disorder apparent in historical patterns of expansion and collapse; read heroic narrative.
In this regard, in what way does the current TV series relate to the core features of the original text listed here? In my view, there is very little relationship and thus the best features of the original text seem to be missed or lost amongst a litany of woeful melodramatic and romantic narrative asides. What then is the point of calling the TV series 'Foundation', when it should, more realistically, be called ' A TV series based on the book Foundation by Isaac Azimov, but having very little actual relationship to the book apart from the barest narrative thread and the name'.
But as I said, who cares!
