This is called “Jumping the Shark” after a Happy Days episode where The Fonz literally jumps a shark while water-skiing, and the show was mostly downhill in quality there and after.
The opposite, and an answer to OP’s question is “Growing the Beard” due to Star Trek: The Next Generation’s apparent increase in quality after Will Riker grew a beard.

Encounter At Farpoint was a fine pilot episode, and I’m tired of pretending its not.
Nice love the beard
