It's honestly part of the problem with the shows in the first place. Cliffhangers are writing tactic that help to retain viewership between episodes and between seasons. The network usually demands them but they'll just hurt the show in the long run as each episode and season doesn't have enough payoff and the show winds up feeling horribly paced and unfulfilling.

Sometimes a show just doesn't have enough content to offer and being forced into the pacing of the weekly cliffhanger schedule kills them and any chance the story had at being fulfilling.
