Sort of, but how else could it have ended? The revelation and the shock was in the subject matter, not in the conclusion. It's not the world's best ending, but its hard to think how it could have ended better. I thought the subtleties of the love interest that had been bubbling under throughout were nicely concluded without being too forced. Considering Dan Brown's reportage style of writing, I was shuddering to imagine there might have been a love scene later on, described using his usual direct and hollow prose. "There was an arousal. It was gradual." etc etc.
