Black Panther - 6/10 - A technologically advanced country has built a wall around itself to block any immigration from its surrounding poorer neighbours, keeping them impoverished whilst it refuses to help out. Their unelected ruler forces his people to work throughout the country, banned anyone leaving unless you agree to act as a spy for the regime whilst he personally hunts down and kills those who do not wish to return. He also restricts the internal movement of his people, preventing them from moving to the more affluent cities and instead leaving them stuck in the harsh outer reaches, either harsh dusty plains or on freezing mountains, where they serve as a border force preventing all illegal immigrants who are escaping repression and rape in their home countries from entering.
However, a brave man comes to challenge this appalling regime, to rip down the walls of oppression and share this wonderful technology with the world yet he is despised by those who have benefited most from it, those who live like royals while the rest can only watch from outer reaches. Eventually the disparity between the haves and have nots erupts into Civil War when an attempted coup on the brave new leader occurs, led by the previous dictator and his SS-like personal guard force who show no mercy, even threatening to kill those they love for choosing a side which wants to open itself up to the world rather than remain in isolation, uncaring to suffering of their neighbours.
Eventually the dictator defeats of brave hero, killing him with a single knife thrust whilst our brave hero refuses to be saved, preferring to die as a free man rather than live as a slave.
I'm not surprised this has been nominated for the Oscars, it's a powerful political story with a real heart and warning about the risks faced when good people try to change a corrupt system.
