I'm currently reading the Wool omnibus by Hugh Howey. It's pretty decent I've been making very rapid progress as it's been too hot to sleep here recently now the summer has arrived.
I haven't seen the Apple show, but maybe I'll watch it in the future when I've finished all the books (I had Shift and Dust as well).
Currently reading Foundation and Earth by Asimov, I absolutely loved the original trilogy so I’ve been reading through the sequels and plan on going back to the prequels after. In my opinion the sequels have a big shift in pacing and sort of the way that the plot develops… not sure how I feel about that. On one hand it is easier to keep up with with less characters, but on the other it feels like the scale of things is much smaller. Trying to not spoil anything. The series is a fantastic read nevertheless!
Difficult to say. If you keep in mind, that he wrote the sequels 30 years or so later and acknowledge that one's views change over such a period, then go ahead. If you, however, expect the same flavor as the trilogy, then I wouldn't recommend reading foundation's edge and foundation and earth. And although these are meant as an introduction to the men behind time, that one makes no reference to the foundation trilogy. So it's fine to just read the end of eternity on its own.
I can only comment on the sequels so far since I haven’t gotten to the prequels, but I’d say if you are open to a bit of a change in pace then it’s definitely worth it. But it’s definitely a bit different, it was written like 30 years later as someone else mentioned. So definitely worth taking that into consideration.
