I enjoyed the book, and I enjoyed this movie. Sure, it might be implausible and they might have gotten some of the locations wrong, but at least it feels realistic and isn't there just because it makes for an exciting scene. Anyway, the film started off slow, but once Langdon was on the trail for the four churches, the movie progressively got better. The events that happened at the third location was shocking and unexpected, with the movie taking on a more violent tone from there onwards. This is not a movie for everyone, and it can be seen as boring for a lot of people, but I thought it was quite exciting and intense once the ball got rolling. The adaptation was done well, but I would have preferred if they didn't change the ending around from the book. I liked how the book had done it in which Langdon was on the helicopter as well. The twist ending where the culprit was revealed could have been more shocking in this respect. Sometimes, things aren't explained thoroughly enough, such that it can become confusing in what would happen next or the clue that Langdon was pursuing. The score used was appropriate and created urgency in the characters' actions. At over two hours long, I do think that it's a longer movie than necessary. While not as good as the book, this was still an enjoyable movie.
