From a cultural perspective, this film comes out at a particularly appropriate moment in modern history and current events. It's probably partially coincidental, but as this is often the trend with films it's also more intentional. As I was watching it, I thought to myself, the title could have been Lincoln: Nothing’s Changed. The white, controlling male majority was so fearful of losing their footing as such that any notion of rights for other groups was considered a traitorous affair. In this narrative, freeing the slaves was a heretical thought for many and sparked physical and verbal vitriol against those who opposed them. Screenwrite Tony Kushner did a masterful job using language to highlight how similar this argument is to issues surrounding gay marriage today or as (literally) laughable as giving women the vote. Yes, we've evolved in many ways as a society - this film is about freeing black slaves and today we have a black president! However, it’s painful and pathetic to see that 150 years later as a society we have not evolved enough to understand that change is good. In that sense Lincoln is speaking to those political blowhards and often time bigots to beg them to see that being on the side of allowing civil rights to flourish is a GOOD THING.
The message of the film is “which side of history do you want to be on?” Watching Lincoln in 2012 it’s so beyond obvious that abolishing slavery is the right thing to do. All the relatively small details like worrying about the economic changes the south will face and the stress that the opposing party has to deal with in this new social structure is pittance compared with the moral obligation of freeing the slaves and the march towards enlightenment. Let's hope that in 150 years (most definitely less, here’s hoping) movies will be made about the struggle towards equality for homosexuals (and women, unfortunately we’re still dealing with that too) and audiences will be shocked to see something that they take so for granted was a hugely polarizing issue once upon a time.
