As I mentioned previously, the film has the unfortunate title of Your Mommy Kills Animals, which has a preaching-to-the-choir feel to it that could limit its appeal. While the name is borrowed from a satirical PETA comic flyer, using the comic and the name in the marketing of this film may be the biggest flaw, one so striking to me that I feel it's important to mention in a review of the film.
You should see this film if you are a documentary fan, regardless of if the title makes it feel like an in-your-face indictment of all things non-vegan. It does its job and leaves the audience more informed than it was going into the film. Even the food company lobbyist has valid statements that are worth hearing.
Most of all, watch this film for what is says about the big animal protection groups that declined to be interviewed (PETA and HSUS). It may be the most enlightening moment I've had while watching a documentary in years.
