It treats the actual facts of history as a worthless and inconvenient irrelevance. At every turn, reality is sacrificed, not even out of a necessary requirement to streamline the narrative, but because the truth fails to conform to the writer's prejudices, and the clichés of contemporary drama.
When presented with this dishonesty, writers usually issue some lame defence about reaching for a greater truth, but what they really mean is they lack the imagination or ability to distill the truth into a compelling story, or they simply don't care enough to try. So instead they feed their audiences warmed-over garbage, and win awards for it.
