I watched this when it aired on TV recently. I thought it was going to be a made for TV movie when it started, however it wasn't. Instead, it's a docudrama; it combines archival footage and reenactments with narration as well as dialogue between the characters. These reenactments aren't brief, muted scenes like on History Channel specials (which I personally don't mind but some people find lame) but filmed as a movie. As a result, the production quality is very high. The cast was exceptional and resembled the actual people (except Wilson which I found odd since he was focused on the most). I thought the actor who played Clemenceau stood out the most.
As for the content, the first half deals with most of the countries involved in the war discussing what they want out of the treaty and the quarrels between them. The last half revolves around the negotiations with Germany. It gives a very good insight into how it all took place. What I found most interesting was that it wasn't just about the politicians like Wilson, Clemenceau, and Lloyd George discussing the treaty at the conference, but also the mapmakers trying to establish new borders and countries (a very stressful job when you consider a few miles/kilometers could mean another war), and the accountants who attempted to put a price on the destruction of the war.
My one complaint is that some of the dialogue was written with too much of World War II in mind. Perhaps the most obvious example is when Lloyd George tells Wilson in private, "I fear a weak Germany almost as much as I do a strong, belligerent one. If she's weak, she's prey to any demagogue who comes along and promises to restore German pride. You know that can happen." Wilson just dismisses the fear and replies, "I've heard that one before." Whether or not Lloyd George said or thought something like this, I can't be certain since I've not looked into it but the way the line is written just made me roll my eyes and think, "Why not just have him mention Hitler already?" That said, this complaint is just a nitpick and only applies to a few lines in the last half of the film.
I found it to be a very entertaining and informative film. When judging a documentary, I take two things into consideration: accuracy and how long it feels. I don't always know enough about a subject to determine if it's accurate but for the perceived length, it did not feel like a long 90 min. I definitely recommend this to anyone who is interested in World War I or even World War II.
