There are no sharks in Star Wars! And nobody under 30 even knows the origin of that phrase anyway.
Also, only tv shows can jump the shark. Movies nuke the fridge.
Maybe they don’t know the origin, but they know what it means. 😉 (and, under 40 is more like it).
I didn’t know there was a separate term for films. That just reinforces my belief that it’s a good thing Spielberg didn’t direct ROTJ. 😄
