This is a “re-re-re-read”, but all the previous ones were a long time ago, when I was a young space cadet, so it has been an almost new experience because there are many details of the plot and characters that I didn't even remember.
Of course, there are issues in this novel published in 1951. The technology is outdated, but it surprises that how is well imagined: holos 3D, personal force shields, ray guns and some spaceoperesque gadgets that in today's science fiction stories are still used. Another issue is, mmm... Asimov and the women, so they have a insignificant role in all this story.
I had this novel highly valued in my youth, now of course things are different., but I still consider Foundation as a great milestone in the science fiction history by the fascinating things it manages to evoke: an empire that occupies the entire galaxy, the psychohistory theory... Excelsior!
Note to think about: the similarities in the Foundation expansion and the relations with its neighbors and the Culture series by Iain M. Banks.
