Good review. Historically accurate as well.

It's perfectly okay to find Lincoln great, but to grant him greatness beyond question, that's too much! Everyone's alleged greatness must be questioned, all the more if bloodshed and breaking of rules is involved. Lincoln presided over unprecedented carnage and devastation and it must be allowed to doubt if all this was necessary or appropriate. No one who sends men to battlefields for the sake of an idea can expect that everyone sees eye to eye with him. And it was an IDEA that the Union must be preserved. Ideas, however great they may seem, must not be accepted without discussion. It's the only way of finding out if they are worth dying for. I'd argue that the price for the preservation of the Union exceeded its value by far. As the value itself was obviously very high, I'd also argue that acquiring it at such a price was nevertheless appropriate. It's just not something that I'd call great.
