Why Watch? While some documentaries tug at your heartstrings, Werner Herzog rented a truck with a Hemi engine to do the pulling here. The anti-texting-while-driving movie starts off with a hammer to the chest and then gets more intense from there, piling on four people’s harrowing experiences with accidents that altered lives. Obviously Herzog is a master filmmaker, and his abilities create the heaviest sense of gravitas possible, but it’s really the sober words from the participants that provide the most profound devastation. Those raw elements coupled with the toweringly unimportant text messages that resulted in deaths and injuries creates a film that’s as vital as it is difficult to watch. Human frailty emerges with themes of forgiveness, bitterness, loving care and costly lessons. Ultimately, it’s a first-rate exploration of something very, very small that can cause great harm.
