A good portion of the book hinges on ambigrams being the most miraculous inimitable creation, yet when we meet them they are anything but. They are barely legible unless you’ve some idea of the word you are looking for - any 13 year old with a tumblr account has seen better ambigram tattoos that Brown offers us in this book 

the characters felt flat, especially the only female lead who was used as a romantic interest and a plot device, her body unnecessarily sexualised at all manor of occasion from the moment we meet her, to the very last page of the book. 

The plot dragged on to a very predictable plot twist to avoid making any political statement. 
 

Okay for an airport read I guess 2/5 
 

Brown needs to spend less time kissing his own ambigram and more time talking to a physicist

The Catholic Church’s circus tent is about to come crashing down. Dan Brown is incredible at creating a fast-paced while still multi-layered thriller that at the same has the spectacle and religious esotericism as an Indiana Jones film. (Robert Langdon is effectively Indiana Jones without the aesthetic) The religious and artistic history entranced me like hypnosis—Christians stole the practice of “god-eating” from the Aztecs after conquering their empire. Some of the plot points seemed a little unnecessary though—why does Robert go into the helicopter? I did the love the fast pace but slow burn of the reveals, like the dead Pope actually being the camerlengo’s father and not just his foster father, and the camerlengo’s reveal as Janus. Vittoria and Robert are a cute couple, and they are definitely a good match—she’s determined and flexible (literally and figuratively) and he’s quiet and compassionate. The scientific theory, though advanced, is clearly and concisely explained to the non-scientific mind. The backstories (for Langdon and Vittoria especially) are incredibly compelling, like how Vittoria came to meet and grow up with the man that would adopt her. The Hassassin’s deadly inspiration and glorious delight in his cruelty weave a spell-binding villain. But the one of the most significant elements of the story is the fact that you can truly walk this Path of Illumination—from “Habakkuk and the Angel” in the Chigi Chapel in the cathedral of Santa Maria del Popolo (Earth—Terra) to the “West Ponente” relief in St. Peter’s Square (Air—Aria) to “The Ecstasy of St. Teresa” in the church of Santa Maria della Vittoria (Fire—Fuòco) to the Fountain of the Four Rivers in front of the church of Saint Agnes in Agony in the Piazza Navona (Water—Acqua) and finally to the Church of Illumination within Castel Sant’Angelo. The path is real though the story may not be. Let angels guide thee on thy lofty quest…

I admire Dan Brown for his ability to create these kinds of page-turners full of interesting facts. I'm not a huge fan of action books or movies where everything is centered around villains and violence, but all the nerdy stuff in this book surely made up for it :)

On the other hand, I really dislike Brown's way of writing characters, everything from creating backstories interesting enough to describing them in present day and action. I mean, of course Robert Langdon is as perfect as Brown's wanted him to be (bet he created him as a perfect version of his own self), but oh god, ARE THERE MORE TO FEMALE CHARACTERS THAN THEIR BODIES? Obviously there should be, but I wouldn't recommend using Brown's books as a guide to writing women. Or, tbh, any other characters either, so very one-dimensional, stereotypical, (and even racist) he made them all (apart from Langdon ofc). Especially the assassin — his actions and overall villain-ness didn't frustrate me nowhere near as his personality was written to be.

So, overall the story was adventurous and entertaining if you just treat most of the chacters as "necessary implementers to the required actions" and ignore their personal traits. Wouldn't recommend if you dislike science and/or history. 

Im Not Sure, I really Like it the First half but Then Well what
The only poc were a camera Woman who got talked down to by a Rookie News Guy and a murderer/almost-rapist.....

Victoria lost her dad, got almost Killed, knocked Out almost raped and then she Just jumps Landon....
Landon got almost crushed, Shot, drowned, knocked Out, Fell from the Sky and then drowned almost again....

The plottwists Well I think at 2/3 that I suspect the CERN Guy, and the bretrayl from the guard came Out of nowhere
And Then Just everybody dies...nice

It is an entertaining re-read. It is not my favorite Dan Brown, but it is a compelling story of adventure. There were portions that I just skimmed. I love googling the sculptures mentioned and seeing the detail and hard work put into the book
