From Wiki: "Jumping the shark is a colloquialism used by U.S. TV critics and fans to denote the point in a TV or movie series at which the characters or plot veer into a ridiculous, out-of-the-ordinary storyline. Shows that have "jumped the shark" are typically deemed to have passed their peak, since they have undergone too many changes to retain their original appeal, and after this point critical fans often sense a noticeable decline in the show's quality."
I sure hope your take on that is correct and I believe it may be.
I have to add that the actual term JUMPING THE SHARK came from an episode of Happy Days when Fonzie and the Cunninghams were visiting Hawaii. The scene to which the immortal “JUMPING THE SHARK” refers to was the one where Fonzie actually “JUMPED OVER A SHARK WHILE WATER SKIING. That was even too much for the most diehard Happy Days Fans apparently! That was the moment the once popular show started falling in the ratings.
Nailed it.
