I thought it did drag in every spot, and I found it so boring because it always took me 20 seconds to get the answers to all the puzzles, while the main character, who's supposed to be a professor, took 3 chapters each. Luckly in the movie they cut the most embarassing ones, as Robert and the Master taking four pages to recognize Leonardo's backwards writing, while mistaking it for... hebrew writing?? What?? They also keep one magic cilinder, cause more than one was really too much to handle. Anyway, besides that, it was really funny, and full of suspence and great actors, so don't miss it! I hope you'll be able to see it in a cinema, because it's so beautiful to see on the big screen (dark lights, such an interesting cinematography...).
