The thing about Brown is that he's a mediocre-at-best writer with really fascinating ideas. If you spend too much time analysing individual scenes and sentences, then you're going to start to see the cracks, big and small. Big cracks like world-renowned scientists jumping to ludicrous conclusions, and small cracks like world-renowned scientists suddenly knowing nothing about a subject so that Robert Langdon can inform them (and the reader) of some exciting tidbit.
And Langdon himself must be the stupidest genius ever written. He knows absolutely everything about everything until it's convenient for him to not know something so someone can explain it to him.
BUT, for some reason, Brown's plots and codes and puzzles are interesting enough to... kind of make it okay. At least for me. I love all the information about history, science and religion. I love how you can look up the organizations mentioned and find that they are all real. It's very much a plot over writing book, but sometimes that can be exactly what you need. Mindless, pageturning entertainment.
In Origin, famous scientist and billionaire Edmond Kirsch is about to make a world-changing announcement. His research and technology have led him to make a discovery about the origin of humankind, as well as their future destiny, that will shake the foundations of the world, tear apart religions, and change absolutely everything. He has essentially found answers to the two questions: Where do we come from? and Where are we going?
It's hard not to be drawn in by these universal questions. Then when the announcement event goes horribly wrong and it seems his discovery might be buried forever, Robert Langdon and Ambra Vidal must go on a clue-solving, code-breaking spree across Spain to uncover Kirsch's discovery. Throughout, all I could think was "what could his discovery be?" It would need to be something dramatic enough, something with impact... and, well, personally I loved the reveal.
