Though 'Moneyball' had the talents of screenwriters Steven Zaillian and Aaron Sorkin going for it, they weren't baseball insiders.
Being brave doesn't mean never being afraid, you know. It means going for it anyway because you know it's the right thing to do.
For me, if the writing and - by extension - the subject matter and the characters are all good, it doesn't matter if it's film or TV. Each medium has great things going for it.
