As a Canadian who grew up in Canada, I found the movie to be quite interesting, as it showed 7 important historical events that happened in China since the founding of the new China (Directed by 7 different directors). A bit patriotic certainly, but this isn't the first time a movie is patriotic (wink wink Hollywood!) and I don't really see anything wrong with that. I'd say overall, its a good movie and I would rate this 8/10.
Some of the negative political comments in this review section here are certainly way over the top exaggerated in my opinion.
