I've always thought sequels wend their way slowly downhill and this is no exception. Decently written, as always, but by this time the Foundation series is highly repetitive - how many times must we (and every other non-Seldon character) be told that psychohistory is hard, hard, and will likely never be practicable? Because in the last few books I have the impression that's all I've been reading. (And the few occasions on which psychohistory does manage to achieve something seem indistinguishable from common sense.)

And yet, the end of "Forward the Foundation" skips over from "hard, so hard" to "all done!" It doesn't say how, the difference is too jarring, and I'm left with the impression that the book is there pretty much solely to wrap up the series and be done with it. Getting on to blood from a stone levels of how-much-more-can-be-wrested-from-this-series level of exploitation, I think.
