I tend to be quick when it comes to using the term "jumping the shark", perhaps much quicker than most fans of things. The reasoning behind this is because jumping the shark doesn't mean the absolute worst episode ever coming out and now the show can't possibly recover. That's what I call just becoming a bad show. After all, hitting rock bottom only means you can go uphill from then on out. I mean, just look at Sonic the Hedgehog.
When I think of jumping the shark, I usually look at the point where the seeds are sown for the future of a show, and generally the point in time in which tonal shifts were being made for the worse. This can for many reasons:
- The budget being sliced
- New writers coming in who can't write already-established characters
- Stories that get increasingly more clichéd (clichéd plots are a show's worst nightmare IMO, because a clichéd episode would lack the originality and tone of the rest of the show)
- Characters getting flanderised
- Typically a show getting more popular could also mean the network wants to milk it for all that it's worth
Then the two big ones that can kill a show's reputation forever:
- Trying to be current and with the times
- Flat-out insulting the haters, which in turn will alienate you entire audience
The Fairly OddParents is mostly terrible with the former, and Teen Titans Go! derives pleasure from the latter, with the excuse that it's meant to be written lazilly, which keeps me from wanting to even watch the show.
Conversely, jumping the shark shouldn't really be the earliest possible point in which these microscopic problems can be detected by scientific instruments, but generally when these problems begin to affect the viewing experience.
Now for a list of 3 shows and where/why I think they jumped the shark:
SpongeBob SquarePants- Best Day Ever (Season 4, 2006): It was simply where Nickelodeon started to become too attatched to the series, which is the number one complaint that people have had with the show, regardless of it's incline in quality over the past few years. Couple this with the "Harveygate" crap that arose about a month ago (C.H. Greenblatt, the creator of fellow Nicktoon Harvey Beaks, expressed annoyance with the executive of Nickelodeon and said that SpongeBob's popularity is flat-out keeping other Nicktoons from growing and prospering), and this was definitely a bad move on Nickelodeon's part that sealed the fate of SpongeBob as a cash cow's cash cow.
The Simpsons- Saddlesore Galactica (Season 11, 2000): The Simpsons has always been about taking stabs at it's audience, mostly with Comic Book Guy's fanboyish nature, but this took the criticisms of the Scully era (Season 9-12; 1997-2001), and blew them out of proportion and not making sure that they were funny. When I think of The Simpsons, or at least The Simpsons of the 1990s, I think of a show that always tries to be funny. This just feels like "Look at this thing that you guys hate, now it's even worse! U mad bros?". Did the "U mad bro?" phrase even exist in 2000? I'm not jiggy enough to find out.
Doctor Who- The Twin Dilemma (Season 21, 1984): I know not many of you would be interested in the Classic Series, but hear me out. Everything about this just screams "Bad decision", particularly it's placement in the season. It's the only Post-Regernation serial to be the finale, therefore not giving the audience enough time to get accustomed to the new Doctor while also not giving the writers a good amount of time to develop the character. As such, we get the infamous scene where the new Doctor strangles his own companion in a fit of rage. Slightly justified rage, but still, it aired right after The Caves of Androzani, one of the greatest serials of all time, so it's barely excusable that writing like this should follow a classic. Sure there were still good stories until the Classic Series' rock bottom in Season 24, and the two seasons following it, but the audience reaction to this serial was sour enough to affect Doctor Who's reputation as a feasible show for the rest of the 80s and 90s.
My Little Pony: Friendship is Magic- The Cutie Remark (Season 5, 2015): I'm pretty sure, as a brony, you'd know why this is what I consider the shark-jumping point by now. It was rushed, clichéd, barely used the Mane 6 as a group, gave Starlight a bad reputation, with most rightfully labelling her a Mary Sue, it came at a point where many of the old writers were being replaced with inexperienced ones, the time travel makes little sense compared to It's About Time, which wasted the potential of all those alternate timelines, and reforming Starlight and making her the protagonist for the next 2 two-parters makes me feel like the Mane 6 being a group that saves the day is a completely worthless concept, despite the earlier episodes showing otherwise.
