Though it is nice to hear that there will be a film that portrays African-Americans in a positive way this does not mean the film will automatically have any significant value as a film. It certainly doesn't mean the film won't "whitewash" other aspects of its theme(s), characters, or plot. In point of fact without ever having seen The War Room (I have seen the trailer) I already know that it will be whitewashing its main theme. According to Jonathan Merritt's review:
"The fifth feature film produced by successful Christian moviemakers Alex and Stephen Kendrick tells a story about the power of prayer."
Since the overwhelming majority of well designed scientific studies have all reached the conclusion that prayer does not work, the idea that there is such a thing as "the power of prayer" is complete bullshit. The few studies that found any merit are flawed and still don't show it as having any more significance than a placebo. Basically, it is all about emotional appeal and willful ignorance. It is dishonest propagandistic tripe. It is also interesting to note that the short trailer that is available at Internet Movie Database is chock full of militant language and imagery. That's a rather disturbing take on morals/values. If you have family and/or marital problems go to "war". So much for the notion that Christianity is innately loving and peaceful.
