Please don't list this on a work's page as a trope. Examples can go on the work's YMMV tab.
Tear Jerker: The Karate Kid
Original films:
Mr Miyagi's entire backstory, from leaving the one he loved to leave a death fight, to marrying but forced to go to war thanks to racial prejudices, only to lose his wife and unborn baby to childbirth while in combat.
2010 film:
The car smashing scene. Made worse by the fact that he caused the car wreck that he's reliving that killed his wife and child.
"Every year, I fix the car. Still fix nothing."
The moment where Dre is injured and Han runs onto the arena floor comes surprisingly close.
