Does Stephen King’s “Under the Dome” get any better?

I liked The Stand and IT by him (already used to the bad endings and I know Under the Dome follows this rule).

I saw this recommended (although with a huge caveat) on threads about survival/apocalyptical scenarios. Already read The Road, Swan Song, Station Eleven and World War Z this year (you might get my point on what I am looking for).

I thought the dome idea was interesting, different from plague, zombies or nuclear chaos, so I started reading it and OH MY GOD, his writing is insufferable! I don't remember it being so corny on his other works?

I am 10% in and only now one character has started thinking about long term scenarios. I watched the Simpsons movie when it came out and I am starting to think that it seems like they did it better…

If it does not get better, does anyone have a rec for a book that would fit this list? People struggling to survive in apocalyptical scenarios.
