It's interesting that you ask why without having any theories. Four female leads, beating up a male bad guy, feminism.
"Roughly half of white adults (49%) say feminism is polarizing, compared with 34% of Black and 36% of Hispanic adults. Similarly, while about a third (32%) of whites say feminism is outdated, roughly one-in-four Black (24%) and Hispanic (26%) adults say the same." [1]
Shouldn't be hard to think of a reason why some people hate Death Proof and other obviously feminist or female-led movies that are consequently suffering due to the bias (The Marvels, The Female Ghostbuster Reboot, Star Wars 7-9, Jupiter Ascending, Wonder Woman, Madame Web, Ocean's 8, She-Hulk).
Although, tbf, Death Proof had half the runtime of a normal movie. And being based around crashing a car as a murder weapon is kind of strange due to its inefficiency.
