Just as S.D. Smith's goal with The Green Ember series was to create family-friendly stories with classic values, a Green Ember movie (or at least films in the same vein as Smith's storytelling) would be great in our modern times.
I probably don't have to remind you what is happening to our modern culture, and I won't really mention anything specific here. However, for those who are Christians or at least hold to conservative values (Smith does both), the state of modern entertainment should be a wake-up call. The media (in all forms) is by far the most influential voice in our modern world. We need some more entertainment with an old soul.
