[Quick Summary: When a teenager accidentally gets sent back to the past & meets his parents, he must ensure they fall in love, or he'll cease to exist.]
I was really worried for Marty McFly. There are real, urgent consequences to his situation.
If he doesn't get his dad to the dance, his parents won't meet, & he'll cease to exist.
If he doesn't push his mom toward his dad, they won't fall in love, & he'll cease to exist.
If he doesn't find Doc, he's stuck in the past without any help.
If he doesn't get to Main Street at the exact time, he will miss his one chance to get home.
If Marty fails, the world won't end, but the consequences are important TO HIM. And that's why I really worried.
WHAT I'VE LEARNED: Tell me what is so urgent. I need to know why the character MUST succeed.
