Robert Greenwald continues his string of activist documentaries with Wal-Mart: The High Cost of Low Price, a rallying cry against what many consider to be the epitome of sleazy big business that targets and even has a hand in creating America's lowest economic class. While obviously biased, the film is infused with enough firsthand human drama and shocking statistics that it's hard to think that it can't have an impact. Sadly, the culture it's unleashed upon either already holds its own opinions on the matter or the people that really should see it probably won't. And though striking in its nature, the documentary has come under some valid criticisms that it doesn't shine a light on the consumers who continue to shop there. While that concern could be made into its own film, it just might be the one topic that Greenwald doesn't touch, and because of that, it's almost as if he's glossing over that fact or turning a blind eye to it. Still, this is an important piece of work that will no doubt reach an audience thanks to the ingenious grassroots marketing campaign with which Greenwald has aligned himself.
