During the covid shutdown I decided to revisit old favorites and maybe discover new ones. I had already read the three original Foundation books as a teenager and loved them . I read one of the add-ons that Asimov wrote later.
It's fascinating to me how much my literary taste has changed, especially since I started writing professionally in 1996. Of course I devoured all the craft books I could, and even wrote one. The unfortunate aspect of this is that I now read old favorites with an extremely critical eye.
The original series is undoubtedly brilliant, vast in its scope and unpredictable in its plot twists. The add-ons, like most unplanned additions to series, are not very good. All seven books are marred by spectacularly clunky writing. In his add-ons, Asimov ambitiously attempted to add aspects of his other books and tie everything up with a neat little bow. The effort comes off as labored and clumsy.
Worst are the last two books, Foundation's Edge and Foundation and Earth. They star a spectacularly unlovable character, Golan Trevise, and Foundation and Earth especially is almost unbearable because of his rude, angry presence. I finished it only because I wanted to find out what was going to happen.
I guess this series is worth reading if you are deeply into science fiction and want to read the old masters, but if you are used to excellent writing, you will not find it here.
