The logic of tyrants

I should have read the novel. I guess there's an idea somewhere why the director Ron Howard had to make the movie so confusing and fast-paced, it's galloping like a race horse on LSD. The countless of flashbacks don't help. Otherwise it's a typical Dan Brown mystery where the professor Langdon runs (literally) through the maze of riddles and betrayal. Read about the controversy surrounding the changed ending, apparently the novel had an intelligent and ambiguous ending and the movie watered it down with a happy one. Typical Hollywood, never fucking liked Ron Howard's films the first place.
