It's the same story with tons of films: Taxi Driver, Joker, The Boys, Watchmen. They get universal praise from the left and right.
The Left: "This insightful satire shows the protagonist's slow descent from obsession and inceldom into terrorism and psychopathy. It serves as a stark reminder of how these thought patterns are the beginnings of a societal tragedy."
The Right: "I fucking love this guy. He just shoots the people he doesn't like. Based. Highly recommended."
