One of the great (and most likely terrifying) things about making network television is the messy nature of it. Shows are not filmed entirely ahead of time. Adjustments can be made midstream if characters or story arcs aren’t being effective. Ineffective shows can make tweaks in a last ditch effort to save itself from cancellation. Popular shows can quickly remove characters that cause fans to have a miniature internet riot (I’m looking at you, The Good Wife). These shifts in story arc or enhanced character development aren’t always successful, but plenty of shows have taken the opportunity to write themselves out of corners as the season progresses.
