I second the vote for National Treasure. History buffs like us have to set aside any skepticism about the accuracy or even possibility of the plot happening, but then the movie gets fun. You can see why the MSM reviewers hated this movie, it revels in American history, honors hard work, loyalty and family, and is a movie you can take your kids to that isn't a cartoon.
Roger that!
I've been wanting to see it since I heard about it. just haven't found the time. :-(
