I was angry at him for taking such an excellent start to a novel, and then spending... what, 300, 400 more pages, just wasting it.
I think the part where the anger really took over, as my main feeling toward and about the novel, was a scene he wrote that exists only to have one character explain another character's motivation "to them"—but actually to us, because we'd spent the last 1/3 or so of the novel with a character whose motivations and behavior didn't seem consistent, like Stephenson had recycled the early-in-the-book character straight into another role that was actually a whole different character, without explanation, without transition, without foreshadowing, without the character themselves seeming to reflect on their own change (which might have justified this scene), without doing the work to make it fit. Moreover, and as a sign of just how "whoops better patch that up without actually putting in any effort" that was, the explanation is entirely lame and unconvincing.
It felt like a chapter that got inserted because test readers or his editor went "WTF?" about all that, and it was just so, so lazy and bad, and retroactively made the treading-water-and-pointless-but-not-offensive middle section of the book worse, to know that, no, it wasn't going somewhere good, Stephenson just wrote it poorly and now, at the end, he's lazily writing his way out of his own mess, rather than fixing it.
(this is the scene between—and I'm a little fuzzy on the characters, as this was years ago—the Chinese emperor-dude and the father who tried to get an off-books Primer for his daughter, from the beginning of the book, with the scene in question occurring, IIRC, near the beginning of what you might call the last act)
