I can’t talk about all the mystical, metaphysical mumbo-jumbo, or else I’m going to start punching my laptop. But I think I can comment on a few things that really bugged me. If I keep those things minor, I think I can refrain from punching my screen.
(1) What’s the deal with Dan Brown referring to his characters by their full names throughout the novel? Not every single time, but really, in Chapter 121, do you really have to refer to the main character as “Robert Langdon” instead of “Robert” or “Langdon”? It’s not like he’s a minor character, and it’s not like there are hordes of other Roberts running around (or any others, really). If Brown doesn’t like the sound of simply “Robert” or “Langdon,” then he really should have given him different names. He also does this with both Solomons, the Architect, the dean, etc.
(2) Were his big reveals supposed to be, um, reveals? The identity of you-know-who – were we NOT supposed to know that? Or the final location of the stairway… again, was there really ANY other possibility?
(3) And what was the deal with withholding really, really minor secrets? He kept what “SBB” meant from us for many chapters. Were we supposed to say, “OMG, ‘SBB’ doesn’t mean ‘Senate Basement B’ but rather ‘Sub-Basement B’!!!”? He did the same thing with the USBG’s identity. It was a Botanical Garden. Sorry to spoil it for you, if you haven’t read it, but it has absolutely – ABSOLUTELY – nothing to do with the story. But he kept it a secret anyways.
(4) Sato’s motivation was really, really weak. Matter of national security? More like a matter for the National Enquirer. Yawn.
(5) Did Noetics have anything to do with anything? No. It did not.
(6) The liquid in the coffin – why wasn’t it water? Was there any reason for it to be what it was instead of water? Did the bad guy have any reason to not use water? No. He did not.
(7) Were there any secrets that Langdon and Katherine couldn’t have gotten by sitting in a lab with the stone pyramid, the gold pyramid, and the cube? No. There was no reason for them to go anywhere other than some sort of lab (or kitchen!) where they could have poked, prodded, burned, frozen, dropped, etc. their tools. It would have been just as exciting.
I had more, but I’m starting to feel monitor-punchy. I don’t think I’ve actually disliked a book before this one. I’ve read some poor ones before, given up mid-way before (I didn’t on this, as I was listening to it on a road trip), then forgotten them. But I’ve never actually expended energy before loathing a book before this one. Kudos to you, Mr. Brown!
