I agree, the movie's a bit of a non-issue compared to what the author of the article (and the director) wants it to be. But it still serves as an example of what's wrong with these kinds of efforts to improve the image of atheists. The director himself says:
Obviously one of his biggest points in making this movie is the atheist character. When you draw that much attention to an issue, it's a horrible idea. It's like LeBron moving to Miami. If he had done it subtly, no one would have been paying attention and his mediocre transition would have gone much less scrutinized. But when you make it your specific goal to promote one aspect of something, that's what people are going to look at first. I think that's the worst possible approach to improving atheists' standings in society.
