Based on the Pulitzer-Prize winning book means something. That same author wrote 1776 about George Washington, and his attention to detail is astounding. Paul Giamatti performs the role of John Adams with such precision that at times, you wonder how close to reality he comes. Laura Linney makes an incredible addition with her role as Abigail, and the interaction between husband and wife is superb. All in all, easily one of the best HBO specials to ever reach DVD and should be in every DVD collection, even for the history-challenged.
What's great about it: Epic Storyline, In-Depth Details, Quality Actors
