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.
I'm taking that to mean "might have mentioned something political incidentally but doesn't ram the author's views down your throat like modern media does and leftards try to deny by claiming it was 'always' political".
Basically anything with John Wayne in it, especially now given that they kvetch over his very existence.
The first two Dirty Harry films. The first one has a retard that gets worshipped by the media for "duin nuffin wrong" before he gets a bullet to the dome. The second made Pauline Kael cry even harder than she did over the original; that alone is worth your watch. These are accidental because this was literally <5 years removed from Eastwood's spaghetti western stint, and he didn't realize how pozzed the America he grew up in had become.
Taken (2008). Cheesy, yes, also a shameless rip-off of the first season of 24 (down to the daughter being named 'Kim'), but with an excellent message at the heart of it; to protect what's yours and make anyone who threatens that harmony pay dearly. First sequel's fairly good, though the third one is garbage.
