It's an eerie feeling, sitting in a darkened theatre, watching various parts of Rome explode or erupt in flame ("Angels and Demons") when an earthquake hits.
Wow, those Illuminati sure are still powerful!
I liked the movie, but I see several reviewers were disappointed. I thought "Angels and Demons" was a better novel than "The Da Vinci Code." Easier to follow, in any case. I really admired the fact that Dan Brown observed Aristotle's rule (and the movie followed it too): the action should take place in a 24-hour time span; it makes for a tight drama. If nothing else pleases the viewer, then at least the shots of Rome are spectacular, all the more so when you consider that the Vatican wasn't cooperative (surprise!), and a lot of footage was filmed in England.
(And Ewan McGregor is great eye-candy.)
As for the earthquake (which we felt), I arrived home to find a lot of stuff on the floor and pictures hanging crazily on the wall, but no real damage.
