This true story—and case—is presented almost perfectly, my one nit being Rachel Weisz: She is nails-on-a-chalkboard to me. I struggle every time I see her. Can't quite put my finger on it and don't know why, but that—plus her obnoxious portrayal here of scholar Dr. Deborah Lipstadt—is hard to stomach.
Excluding that, it's perfect in every way: Sleek, simple, and really packs a punch.
I suppose a few factoids, photos, or brief news clips preceding the end credits would have been nice, so here's a link to Lipstadt's work, if interested, and what came of debunked historian David Irving.
