Butterfly effect.

   Butterfly effect, apart from something everyone talks about when wanting to look cult, is a damn wicked curse in every single story plot. I mean, look at these until dawn (we love u rami) or life is strange (who cares bout that blue-headed bitchie) or life is strange two (marry me finn) honeybees, all dyin' around like stupid because you flipped yourself the wrong way while sleeping. Look at my hunger games, boy! Imagine, say, Haymitch hadn't upset Effie messing with her hair on the reaping, and thus she would've been in the mood to play with the boys' urn as she did the girls'. She would've stirred the slips and my good old Malarkey would've returned home that very afternoon, safe and sound. And what's the plot without him around? Katniss climbing trees and dying after Cato finally realises they can just burn the wasp tree down? Crappy. No love story. No rebellion. No Johanna. And all because Haymitch was not drunk enough to displace Effie's headset. See? Butterfly.
