It’s actually tougher to find elite duologies than trilogies, because almost every time a movie gets a good sequel, a third one eventually follows.
Remember, if there’s a third film, it’s disqualified. (So no Godfather, Lord of the Rings, etc.)
My picks:
- The Hustler / The Color of Money
- Blade Runner / Blade Runner 2049
- Kill Bill: Vol. 1 and Vol. 2 — though that one’s kind of cheating.
