National Treasure Book of Secrets is so much like the original, the writing isn't very tight and the character development doesn't exactly make sense and there is one part where I swear they were writing the film to go one direction and then went another, (because actors reactions don't make sense in that spot)... I still have to say that I really liked this film. It was just fun. Helen Mirren is great in the film. It's a good escape from the depressing weather we sometimes have this time of year.
