Even though based on history, so-so on execution. Difficult to suspend disbelief with some of the actions that characters take. Doubt there is historical basis for supposedly veteran sailor taking over ship single-handedly only to jump off and swim in full armor (albeit scale and mail) quite a distance to shore. Would not the historical figure have sailed it? That and other nits that didn't jibe caused my disbelief to come crashing down. Too bad. Beautifully shot.
