At one point, they talk about why Christian art is so bad. Brian godawa explains:
The question is how well can you incorporate your worldview into the choices of the characters, rather than plopping it on top by having scenes where people explain everything. That's the problem with Christian stuff, they feel they have to explain things because if you don't it won't be clear. It's good intentions. They want the meaning and the message to come across clearly. But but in so doing, they don't understand how art incarnates meaning so you don't always have to be explicit in words.
