The opening was a bit off-putting, a saccharine, contrived scene to simply enable recitation of the Gettysburg Address in a very sappy way, but once that was behind us, the rest of the movie was superb. Day-Lewis was near-perfect as Lincoln (at least to my mind's eye & ear).
Tommy Lee Jones steals the film as Thaddeus Stephens.
The opening aside, a great film with marvelous acting. Even James Spader. Very worthy of your time.
