Luck.

I read the first Chronicles, all the while not understanding or believing the motivation of "our hero" . I had no sympathy for him from the beginning, and even less as time went on. Once I got over this dislike, I enjoyed the story (although the rape still leaves a bad taste, even all these years later), and some of the world-building was brilliant (although depressing and derivative), but I hated the main protagonist. I thought that in general the story overcame his hero, and the ending tied everything up nicely.

I think its due to the effects of Leprosy and teaching of his doctors of how he must survive and he did what he did due to this, but you know all of this.
Passes the time and as I am not at all up to date on fantasy / sci-fi I start to look backwards
for books to  read

In his "How to write good," Michael O'Donoghue includes advice on endings.  This season of Silo contains both this and other advice offered regarding "The Grabber." to help lure us into viewing yet another season.  If someone could do something about that awful oppressive soundtrack, I'd appreciate it.

Good luck, goldie.  I had to look those up.  They sound involved, like lots of fantasy novels, but with some compelling protagonist.  I don't know that I'd enjoy them, given chris's descriptions.

I am reading another futuristic novel, "Never Let Me Go," by Kazuo Ishiguro.  About clones raised to donate their organs.  Told from the perspective of one, while still in the exclusive institution where they are raised and cared for until adulthood.  The novel is subtle in that you don't really grasp what's going on for a while (and given I haven't finished it, I can't really provide spoilers of any substance).  And then, it's hard to predict where it's going, but probably not to a good place.

I read his "Remains of the Day," which you might know from the film with Anthony Hopkins and Emma Thompson, many years ago, and I can't say that it's a feel good novel, but it does offer keen insights into people's emotions and the structures -- both internal and external -- that prevent them from achieving happiness.  He lives in the UK, having emigrated from Japan when he was 5.  I guess he won the Nobel Prize for literature in 2017.

So far. Morals of story:
1)  It pays to be an engineer.
2)  Never trust politicians.
3)   The future is not bright.

I had to watch the second half of season 1 of The Silo before I could figure out what was going on with season 2.  Now it makes more sense but we'll see if it gets better.  The music is particularly oppressive.

They should have "Filmed in Bleak O Vision" in the opening credits.
