I really enjoyed the first third of the book, the second third was decent too. I had to drop it when I got to the last third, it just became too boring.
Prompted by a comment from someone yesterday, I actually replayed the Snow Crash audiobook in the evening. Comparing SC and SE I notice that SC feels quite juvenile. I didnt notice that as much when I first read it in my 20s. But these days, it feels a bit too much over the top. Contrary to that, SE somehow feels too grown up.
Spoilers. Like, I mean, this isn't a plot summary, but this is in some sense what happens so look away now if you wish you didn't know:
The Primer has been calling her Princess Nell for a long time. Once you realise what's going on with the vast number of "specially adapted" Primers for the orphan girls, that Princess has got a ready made tribe with shared values in the form of the Mouse Army, waiting for her say so.
The whole book has been telling you that in this era what matters isn't control over a land mass, which is what the Fists are fighting for in the Leased Territories on behalf of Han, but a Tribe with shared values.
The Mouse Army shows up, rescues Nell and takes her to her mother. The Victorian Queen recognises Nell as the leader of a novel but important tribe.
The novel is flawed in many usual Stephenson ways (e.g. use of rape in place of actual character development) but I don't know what people expected from these endings, they seemed perfectly satisfactory to me on multiple re-readings.
