Heaps of chinese news doesn't make it out of the country, because it's written in chinese, or published in Chinese (only) news outlets. It's not a cover up.
If a critique essay to this movie appeared in one of the newspapers with official backgrounds, it would be a totally different story.
V can be interpreted any way you want depending on who you think the bad guys are. The Chinese government was established by revolutionaries after all.
At least a dozen former British colonies established their independence gradually and peacefully, with the willing cooperation of the UK. No fighting, animosity, or anything that could be remotely considered a "revolution".
(Now of course, not ALL former colonies separated peacefully: India, The United States, etc. But there are plenty of examples on both sides.)
And how about Iceland?
Anyone who didn't know V before won't care anyway.
it's a meh exaggerated by social media.
