Ultimately, this movie is a Brazilian soap opera. There are intrigues and billets-doux. The pop theme, recorded by an orchestra in Prague, is good but over-used. At least seven or eight crescendos cover various characters when they either grasp each other, look at each other or wistfully stare out windows while thinking of each other.
I didn't mind the historical and geographical inaccuracies. The need for financing seems to have motivated scenes of Pitt and Voltaire. (Was the inclusion of Franklin a failed attempt at American financing?) In fact, these scenes were not necessary since the movie used symbolism. The basic facts arguably fit the presentation. A case can be made that New France was abandoned by France, abused by the Catholic Church and strung up by England. Marie-Loup, get it? In the movie, she is illiterate but very articulate. Indeed, everyone spoke with modern international accents from mouths with white straight teeth. (So what! It's only a movie!)
Jean Beaudin made "J. A. Martin Photographe" which was both a beautiful and sensitive movie with Monique Mercure in the lead. She's in this one too but her presence only hearkens to the past. Despite its flaws, I enjoyed "Nouvelle France" but I'd probably enjoy any movie about the history of northern North America. If you have no interest in such history, this movie will be a convoluted Brazilian soap opera.
