I've read the original Foundation trilogy twice (once in my teens and once about 8 years ago), and I thought about reading it again with the new adaption of Foundation coming out on Apple TV. Or maybe I would read the later sequels (at least one of which I read awhile back). But then I found this latter day prequel on my shelf (that I had forgotten I bought!) and figured I'd check it out.
I can say I enjoyed Prelude to Foundation overall, although parts of it dragged on a bit. You probably have to have a soft spot or at least appreciation for Asimov to really like this. I read the original trilogy as a teenager, which maybe accounts for my soft spot for Asimov. Some people these days complain about Asimov's writing, but I think it's perfectly fine for what he's doing. Asimov was always mainly about the ideas, so if you're looking for in-depth characters or snappy dialogue or whatever... well, you're not going to get that here.
