I disagree. A well-resolved story arc invites the viewer to reflect on—or even re-watch—the entire sequence of events in a new light, giving greater appreciation to plot points which may have been cleverly crafted foreshadowing or clues. A poorly conceived ending gives everything that led up to it a bitter taste in retrospect because it reveals that what was presented as a plan was really just a bunch of writers pretending they knew more about the situation than the viewers.
If the final episode of Breaking Bad ends with some bullshit “it was all a dream!” sequence then it would understandably diminish fans’ appreciation for the series as a whole.
