I never did see Da Vinci Code but I find it very unlikely that this could have been much of an improvement. Angels & Demons is basically a scavenger hunt that’s about as entertaining as watching a scavenger hunt, which doesn't happen to be very damn entertaining. In addition, whole movie is full of plot holes, happy coincidences and contrived twists that you definitely see coming. Eventually, things teeter from minutely plausible to utterly ridiculous, at which point you realize that some people actually take this shit seriously. And then we all laugh, and die a little on the inside.
