Probably because it's many decades since I read Foundation my memory of it is faded, so I'm seeing this series through a different perspective and as a TV show it had become absorbing and fascinating. The first few episodes were a little scattered in the telling of the story, but I presume that something as vast a concept as Foundation would not be easy to convey on the small screen, or even the large screen as a series of movies. I have been impressed by the cast, the CGI and all of the interweaving of the various paths that the different characters are walking, and there have been a number of surprises that I never expected. Moving away from the books, it has proved, to me, to be interesting and as I approach the season finale I am hoping that the series has done enough to warrant continuation. It's never easy to transcribe words in a book into a visual concept and it will always be so when a series or movie is based on a book or short story - there is no means to replace the individual imagination that can visualise what the words on a page are conveying and everyone's vision will differ, so it's no real surprise that the die-hard Asimov fans are wary of the visualisation the creators of the series have conceived.
My own preferred Authors of my time were Asimov, A.E. Van Vogt, Philip Jose Farmer, Poul Anderson and the master of them all (IMHO) Robert A. Heinlein. There were many others, but these were the ones that drew me into their fascinating worlds with ideas that bucked the trends and dared to be, shall we say, a little more imaginative than most
