My dad once said to me, "You give a lot of books three stars." I do.
What can I say? I'm a sucker for a Robert Langdon book (except for The Lost Symbol, but I don't think any of us were here for that...).
If you like the Robert Langdon series, Origin is more of the same. Occasionally Robert Langdon will be so obtuse you'll want to hit him over the head. The descriptions will be ridiculous (I don't think I've ever Googled anything Brown has describing and gone, "Ah, yes, you captured this perfectly." It's always more like, "What caricature were you looking at when you wrote this description?"). Nothing will happen until the end, and you will guess the twist at the very beginning (the twist is so obvious).
Brown talks a lot about religion and clearly did a lot of research for this book but was apparently too lazy to research any African religions at all. At the beginning he writes "an African god parting the clouds and lowering two humans to earth" after specifically naming the Christian God, Prometheus and Brahma. Come on, dude. Try harder.
I plan on fully forgetting the plot in the next week or so. I do this with every Dan Brown book I've ever read. It makes the movies more exciting.
