Because the crime was heresy, the Church is implicated, but the facts show it was a secular event. One facet of the Black Legend that evaporates under scrutiny in this film is the rumor that Philip II, son of Charles V, killed his son Don Carlos on the advisement of the aging blind Grand Inquisitor. But without a shred of evidence, the legend of Don Carlos has been enshrined in a glorious opera by Verdi. The special may be disturbing to young children. There are scenes of poor souls burning at the stake, and close-ups of the alleged torture devices.
Scenes depicting witches consorting with pot-bellied devils are especially grotesque.
For kids, this is the stuff of nightmares. Discrediting the Black Legend brings up the sticky subject of revisionism. Re-investigating history is only invalid if it puts an agenda ahead of reality. For many it may continue to hold more weight than reality. There is the emotional appeal against the Church.
