"but like all of Stephenson's books, finishes ugly."
Hmmm... that's a big statement. The ending of Cryptonomicon apparently had a different effect on you than it did on me.
As for The Baroque Cycle.. I've read half of the trilogy so far.. My reaction?.. Each book is way too long, but is OK once I get into it.. If each of the books were cut in half (while keeping the same essence), they'd be better books (IMO).
