El capitán Barbanegra

The movie is set in the early part of the 18th century. However, when they site a French ship early in the story, it is flying the blue, white, and red flag of modern France which did not come into existence until the French Revolution some 75 years later.

It would also help if there was more character development. For example, other than duty, it is not clear what is motivating the hero to undertake the mission which serves as the basis upon which the story is built.

The settings, which I understand were built in Thailand, are also well constructed and believable as being in the Bahama Islands almost 300 years ago and provide good backgrounds for the scenes.
