Gibson would likely have embued it with transcendent values, but in fairness he took as many liberties with the history of William Wallace and his times as Petersen takes with The Iliad.
True. But the Braveheart both 1) was entertaining, and 2) conveyed the core of the message of who William Wallace was. The prima nochte, French princess, and Robert Bruce variants really didn't alter that message.
Trampling important things into the muck does not make high art.
