Miller did the opposite of a traditional sequel: narrowed and distilled instead of expanding. The ambiguous, amoral world unexplained. The stoic, silent anti-hero. It works. Overshadowing the original, he finds here the balance between his UNIQUE talent for prop & visual based character storytelling and paced, worthful action that make Road Warrior a fine, iconic western on wheels.
(Generous) 9 - Talk about an upgrade. The relatively simpler and less character-centric plot is tremendously offset by far superior visual storytelling and attention to detail, all wrapped up in a grimy post-apocalyptic western vibe. It's also very well-paced, surprisingly funny, and the quality of its car chase set-pieces (even with the infamous sped-up frames) would remain virtually unchallenged for decades.
