It's not too bad, though it's badly flawed in some respects. The marble is still thickly encrusted, and the filmmakers had no inclination to indulge in flinty-eyed review of such topics as, "was a civil war really necessary? -- nobody else had one!" and "what was the real objective of the Civil War?"
The film's POV is that of a Lincoln-circle insider of the first or second ring -- say, Ward Lamon or Allan Pinkerton or Gideon Welles. But not the first ring. They would know the real reason Lincoln came to office determined to fight a war with the South and destroy it.
Spare us your rich fantasy life.
Reading his deranged Obama cheerleading last week solidified that impression. I made the comment before Lincoln came out that if one were interested in the history of Lincoln, Abraham Lincoln: Vampire Hunter might be the more accurate historical choice.
