It's got a bit of a hint of "society is falling apart because of the oil crisis" in the background, which is an interesting period thing. But mostly a revenge film, yeah.

Although I think most American viewers don't really know about it at all and only think of the second mad max film, which was marketed here without the 2? And almost all cultural references about "mad max" are about the road warrior vibe specifically, or thunder dome / fury road now.
