Netflix, Streaming Videos & DVDs

An expression that means "a show will reach a point at which far-fetched events are included merely for the sake of novelty, indicative of a decline in quality."

They could 'run out of a story-line', or, as stated elsewhere, the story had deviated too far from the original premise, some 'characters' have left the show, or the show has simply lost its way.

I have experienced several of these examples or combinations and variations of them. I also find it interesting to see the rate of success with 'spin-offs' - do they make it or not - and why?
