Let's make a list of movies that have based themes, even if the writers and directors perhaps weren't doing that on purpose. Include spoilers if you want, but please mark them in advance.
I've got two in mind.
Appaloosa from 2007 with Viggo Mortensen and Ed Harris. A western about two lawmen for hire who come to a small western town and get hired on to take down a land baron who murdered the previous Marshal. Pretty typical setup as far as westerns go, but the movie introduces a female character about a third of the way through who is pretty realistically portrayed. She has zero action scenes, she quickly starts making moves on the senior lawman, played by Ed Harris, but also tries to get her hooks into his deputy. At some point when there is a falling out between her and Ed Harris, she accuses Viggo's character of trying to make moves on her and Ed Harris's character straight brushes it off by saying he doesn't believe her and believes Viggo because they're friends. There's no 'what if she's telling the truth' drama. She also later tries to hook up with the evil land baron character. Very based themes about the nature of women, hypergamy, positive male friendship, and the untrustworthiness of women.
Side Effects from 2013 with Jude Law, Rooney Mara, and Channing Tatum. A psychological thriller about a psychologist, Jude Law, diagnosing a windowed housewife, Rooney Mara, who murdered her husband, Tatum, and tries to plead insanity due to the supposed side effects of an anti-depressant she was on. I won't spoil the whole movie, but not everything is as it seems, and there is a sordid lesbian romance later on in the movie, where it is revealed who was lying about what and who is manipulating who. You'll be very satisfied at the end when the guilty party ends up getting what's they deserve. Also a lot of based themes about the nature of women, though I don't want to go into specifics due to spoilers.
Reign of Fire is a movie that showed that in a world ending apocalypse, the first things the British do is build a castle, adapt to living in fear and hide to try to wait out a fucking dragon invasion that spans the globe.
Its not until a psychotic American shows up sitting on a tank that they even try to fight back whatsoever, and he has to teach them how fucking technology works (they use helicopters and radar instead of the Brits using a fucking falcon and a telescope) as well as basic biology like "if you shoot things they die."
And just like real life, only after almost all the Americans get killed trying to save them that the Brits grow enough of a spine to fight back and then act like they are the heroes for weathering the storm.
Great movie, but the political joke there is almost hilariously on point.
