DC's Poison Ivy is always one of the best examples of this.

I want to say she is from the 70s? And "evil lady eco terrorist" is both sexy and evil. Except, as time went on, more and more of the readers/viewers started to REALLY like the lady who murders the patriarchy while destroying chemical factories and oil refineries to protect the planet. So she became more of a plant monster and DC Editorial learned how many of us are into bondage and so forth. Which has led to the modern day where she is basically an anti-villain, at best, alongside her lesbian lover Harley. Although the Harley Quinn show did a great job of playing with that with everyone more or less thinking her an annoying goodie two shoes even though she is torturing and murdering children and whatever else her background atrocity of the week is.

But a lesser known example that might actually be one of my favorite movies at this point is Donnie Yen's Raging Fire. Yen plays the hero cop, as he always does, who is older but has morals and butts heads with his bosses who are too political. Except that, years prior to the movie, he was on a case with his protege and partner and they were told to do whatever it took to find a rich business man. Oh noes! His entire unit accidentally kills a suspect and now then Oh Noes, Donnie narced on them because of his morals so they went to prison and had a REAL bad time.

And now they are out and killing the corrupt cops and business people who betrayed them. Also it is basically Heat (right down to getting caught because the psycho killed a hooker) and the movie does a REAL good job of showing why Tse's criminal is the way he is and why Yen's cop is pushed to his breaking point and outright fighting the system he is supposed to uphold when his loved ones are in danger.

Until the final sequence which is the bank robbery from Heat. Except the writers realized the CCP is REALLY not going to like a movie that is this anti-cop so suddenly they are mowing down civilians left and right and lobbing grenades everywhere just to make sure you understand these ex-cops are actually the bad guys. And Donnie Yen and his CCP mouthpiece ass still has it.

Its a deeply problematic movie, like most of Donnie Yen's post 2010s work, but it is also incredibly fascinating when you think of it from the perspective of sympathetic villains and state mandated "tone". Also, like ALL of Donnie Yen's work, it is a beautiful spectacle of martial arts coming from a guy who is even more frustratingly charming than Tom Cruise.
