I am a kind of person who has such a thirst for knowledge (in all branches) and discoveries, even for an adventure. And, this movie is an adventure and quite enjoyable to watch.
I have read a great deal on Masonic history as well the American history. And, there are bits and pieces of histories into this movie, but one cannot get the full understanding or knowledge of histories from watching this movie.
However, I found this movie to have a stretchy plot to which is not new, as it is typical. One would have to keep in mind that this is one of the Disney films, so this movie is suitable for kids as well enjoyable for adults. And, this film is more close to the line of the films, "The Da Vinci Code" and "Pirates of the Caribbean," or so I think.
Nevertheless, this film is fun to watch.
