I saw National Treasure last weekend. I thought it would be a fun movie, but, honestly, I wasn't expecting much. As a result, I was pleasantly surprised. I really liked the movie quite a bit. The history is fascinating, even if woven together in a totally inaccurate way while pushing the conspiracy theory that the Freemasons founded and run the country to this day. Regardless, the movie is a "thumbs up" in my book.
Nicholas Cage does pretty good job as history scholar/treasure hunter. It's easy to see how his character -- Benjamin Franklin Gates -- could get caught up in such an obsession, especially when he grew up in a family that not only had encyclopedic knowledge of history, but had some fascinating documents to back up their crazy theory.
If you pay attention to the details, you will be entertained for a solid two hours and you might even learn something about American history.
