A version of this review appears in Friday's Weekend Life section of The Oklahoman. 3 1/2 out of 4 stars.

Twenty years later, I couldn’t help but cringe at every replay of the explosion, every wide shot of the hollowed-out building, every close-up of the devastation.

Although Oklahoma City has changed dramatically since April 19, 1995, the bombing of the Alfred P. Murrah Federal Building still leaves a mark on the psyches of Oklahomans. I was just a senior in high school back then, but I can tell you exactly where I was and what I was doing when I heard the news.
