The Expanse if the best books series I have read in years and might be the best science fiction series I’ve ever read. The quality does not diminish (in my opinion), and I am glad I didn’t watch the show beyond the first season before reading the books. But there is a lot more than the show covers. I think you can come back to the Novellas later if you like. They are great but you don’t need to read them alongside the main novels unless you are so inclined.

Some are better than others, but they’re all fairly high quality? I’ve definitely read worse than even the ones I’m not super thrilled about, so I’d say it’s worth reading them all if you have the time.

I loved the series

Some of the short stories are hit or miss but they are short and worth reading either way and only short

With most series of this length, towards the end I’ve tended to wish that the author would just wrap things up already so I could find out the ending and move on with my life.

With this series I actually got sad as I made my way through the last book because it meant that the story was going to end soon and I had been enjoying it so much that I didn’t want it to end. (Having said that, I also absolutely loved the ending, which is also unusual for me for a series that is this long!)

Just finished last month and it’s one of the best series I’ve ever read. I haven’t read the novellas so after some time I will reread the series with them included.
