I love how the Highlander franchise handles continuity. Don’t like Highlander II? Highlander III ignores Highlander II. Don’t like Highlander III? Highlander: The Series ignores Highlander III. Don’t like any of the sequels/spinoffs? Ignore them all to your heart’s content; the original film has a perfectly closed ending anyway.
Of all cherished franchises which consist mostly of shit, the Highlander franchise is the one I have the least spite towards, and it’s due to this healthy, organic, blessed discontinuity.
