Jumping the shark. Seems like most shows (and films) eventually go thru this. It is a sign that the show is on it's last legs and the writers reach the point where they run out of ideas and have to insult their viewers with some incredible storyline in the hope of re-energizing themselves. this rarely work as the shows stick around for years and stinking up the airwaves until they finally die.
Name some of your shows and which season or episode they "jumped" ?
SLIDERS season 4 episode Genesis. Some will argue that the show actually jumped in season 3 but i have to vote Season 4. the show did managed to redeem itself in the 5th and final season.
CLASSIC STAR TREK Season 3 pick your episode: Spectre of the Gun, Enterprise Incident, Spock's Brain. Maybe only one episode from the season was worth watching. Shame our beloved Star Trek had to go out like this.
24 season 5. I mean come on man how many ways can you save the world from terrorists? this show played out after Season 4 but hung around for several more seasons. Pitiful.
LOST season 5 and 6. Talk about going from the Penthouse to the Outhouse. this show stunk so bad at the end it was painful to watch the 2and a half hour series finale. I was glad when it was over. we rarely even speak of the show these days....
DESPERATE HOUSEWIVES this show was never the same after we found out what was buried in the backyard (season 1) should have ended years ago...
VOYAGER when they introduced Seven of Eight...
These shows never "jumped" and went off at the top of their games
STAR TREK TNG
