The beauty of being a Christian B is that you don't just exist in the same world that everyone else does. What matters is not Louboutins and boob jobs, but coffee-hour cookies and the power of prayer; whether you approve of the new stained-glass window and what you think about eternal salvation.
How do you weave the idea of redemption into a soap about God-fearing folks who are all flawed? There's a reasonable amount of comedic and dramatic potential contained in that premise, but "GCB" spurns almost every part of that setup.
As you can see from my picture, I am a white guy. Not even a cool white guy. I'm the white guy that black comedians do impressions of. And as you can imagine, like most white people, I do not see your movies.
