The so-called exposure of Hollywood's lies is pretty dubious. Take #1 for example. Commodus may not have killed his father, but he was a notorious sociopath and, yes, creep. One of his favourite tricks was to feed his guests pies filled with faeces and watch while they forced themselves to swallow. And while he did, indeed, die in his "bathtub", that was because he was assassinated there by 1 of his gladiators.
Again #3, the Mayans may have been an advanced civilization, but they were also pretty damn mean and the movie always struck me as accurate.
And re #7, does anyone really care that the film used P-40 fighters instead of the more obscure P-36's? Even if the P-40 wasn't available for another 3 months?
As for #9, I agree. Every Brit I know was BLOODY WELL pissed off that the Americans gave themselves the credit for something the British armed forces achieved.
And the 2 Mel Gibson movies are total historical garbage. No question about that.
