Seveneves

I almost gave up about 300p then again about 600p but I finished the book , from cover to cover.
I do not have any problem with expositions in any book (I actually like it ) but I honestly find that Kim Stanley Robinson does a better job on this than Neal Stephenson (taking Seveneves as a starting point) as I think that KSR when describing Space, ships, planets, etc is way more interesting, compelling and clear. I find the expositions on Seveneves almost boring and with too many ramifications that at the end were not even important to the plot.
On the other spectrum when the plot is actually happening and there is an argument Neal does an amazing job. I would say this book could be like 300p shorter.
For the last third that got so much criticism I do not think it is bad but I sympathize with those who say that it could be just another book.
