I am naturally drawn to historical nonfiction, but I think the story is compelling enough to draw in those who might not otherwise be interested in history. Moreover, the love story and family dynamics of the Adams family (da na na na... ch ch...) is insightful, heart-wrenching, and instructive.
According to David McCullough, the historian and author of John Adams, this movie is extremely accurate.
This is one of the few movies I will probably watch again.
btw... you can probably check it out from your local library.
