As far as I see it, humans could work if implemented as a whole species rather than as individual characters, negating the whole “tag-along character” problem Megan propagated. I think humans could work if they were put in as an extremely distant and ancient post-post-apocalyptic species totally unlike “modern” humans.
 
You know the kind, the ancient species with secrets abound, maybe or maybe not evil and maniacal toward the younger species, steeped in mystery and power. The kind you see often in sci-fi or other fantasy works. Reapers, Chozo, Eldritch Horrors, Goromorgs (sort of), Old Ones, Forerunners, etc.
 
Considering how out-of-whack the technology is in terms of advancement (wooden wagons and drawn carriages one minute, steam(?) trains and airships the next), it wouldn’t be a big stretch to assume most of it came from scavenged and modified human tech. Heck, all of the mythological creatures and weird plants and animals could be a result of human science, perhaps mixed with magic.
 
When it comes to ponies extensively needing human help, I honestly think it’d be the other way around in that situation. Humans would probably be ancient, frightening (carnivorous + ~ millenia of war experience + majority of tech focused on killing things = scary for any species sensitive to war/death), and horribly out-of-touch with the other species, if they were reclusive or recently reawakened from some form of scientific and/or magical stasis, kind of like Luna was.
 
I think humans could work if implemented, but it’d be tricky.

I like that aspect of FiM too. It looks like a sugary, candy-coated fantasy world from a glance at Ponyville, but that’s because it’s a glance at a society run by a prosperous and mostly light-hearted herbivore species.
 
In the episodes that take a look at other bits and pieces of the world, you can see good and bad in equal measure. There’s happy societies and creatures, magical kingdoms, various flora and fauna with magical effects, and other good things. But at the same time, there’s also murderous insect-shapeshifter hives, forests full of monstrosities, migrations of the biggest and most destructive creatures around, and even Tartarus itself. It’s one of the few narrowly-focused fantasy worlds with a believable balance of things both good and bad about it, never skewed toward extremes of rotten or genuine sugarbowl.
 
If that got fucked up, I’d leave for sure.

If the show got legitimately bad.

@Sonlirain- My idea of humans is that they are counterparts to their respective pony, each having a trail similar to her(or his since there will be 1 male) pony partner.

Killing off one or all of the mane 6.

-If they made a Derpy-centered episode  
-If the characters stopped being positive role models and instead became stupid and vapid  
-If the jokes stop
 
I watch it for the jokes and character interaction.

Actually the only thing that would make me not watch mlp any more is if they move on to gen 5 and it’s just like gen 3. Oh god please no.

Actually, the phrase “jumping the shark” refers to an episode that’s so ridiculous it’s can be so bad it kills the show, or so good that all the episodes after that seem weak.

All you people who said “show is cancelled” are tools.

Cancel MLP
 
That’s what

easy, hire tamen antonaides A.K.A tamte the douchebag who made fanfic may cry, after watching that train wreck anything else seems way way WAY more acceptable

They would have to actually do something that makes the show suck, or make a series of bad episodes.
 
THATS WHAT JUMPING THE SHARK IS. NOT BITCHING ABOUT PLOTLINES BEFORE YOU SEE THEM.

The way i see it, Twilight was the “personal student” of “Princess Celestia”, not of professor x or doctor y, of THE Princess Celestia.
 
Wouldn´t it make sense that a princess student who finishes her studies becomes a princess too? Given the episode description Twi didn something that´s really complicated or even impossible for Unicorns and then got Alicorn-change. Not before that.  
So her actions lead her to get wings, not the other way around. She earned those, she didnt got them for free like our world royals do.
 
Its why for me Twilicorn isn´t jumping the shark just a early use of something which i and clearly a whole lot more people than just me expected since the first season.  
As if the Tiara wasn´t a dead give-away.

@Ebalosus  
Humans might be cool as long as ponies around humans don’t suddently become retarded and require help from “Megan” with EVERYTHING.

eh…it’s actually a good question OP (kudos to you).
 
For me, at least, it would probably be a factor of things, such as:
 

OP, “jumping the shark” can only be determined in hindsight. You’re just whining.

I really REALLY don’t care about whatever happens in the show anymore. I just watch every episode once on youtube and come on DB to post stupid comments.
 
Twilight becomes an alicorn?  
Ok just keep her character intact along with her friends and i’ll be ok with this.  
As far as i’m concerned the entire mane cast could be turned into Gryphons.

I’d stop watching if they gave into the haters yet again and actually removed Twilicorn.
 
Why everyone is getting so mad over something I was expecting to happen from season 1 I don’t know. Although the fact it’s happening before The CMC even get their cutie-marks is rather surprising. Season 3 made it extremely obvious from the first episode this was what they were planning, though even with every episode building towards this, it still feels too soon. This should have been the season 4 finale.

Stop making the episodes and cancel the show or just not make it fun to watch. Occasionally when you see something in an episode that may be a nod to us Bronies, it makes it even more fun to watch. Intentional or otherwise. Watch or don’t watch the show. I know I’ll continue to enjoy it. And for once, it’s nice to see a show where a main character has progressed, instead of the same old crap. I.E… wearing the same clothes every episode, in the same grade for years on end, etc….

I dunno, actually; I trust the writers way of handling the situation and I think that this might be a good business move from Hasbro. I mean, back in the days of the Derpy Drama, we also had to remember that we are first and foremost not the target or primary demographic.  
Which is why I say I trust the writers, and I think that everyone should. We have too little information on how this is going to devellop, and what’s gonna happen afterwards, so just sit back and enjoy the ride. So far the team hasn’t let me personally down since I don’t really like the idea of head-canon to begin with; I just take the show as it goes, and I enjoy it.  
Offcourse there are episodes that I enjoy less and some that I enjoy more, but it still comes down to the same thing; It’s a show for kids.  
Throwing temper tantrums just because you see something that you dislike is kind of juvinile and goes against the principles that the show itself teaches. Think about that for a sec.

Becoming boring or devolving into self-parody.

I’d only stop watching if they disbanded the royal guard.

how about you fuckers hold your “jumping the shark” bullshit until the episode actually aired? would that be an an idea? have any of you “THE END IS NEIGH!” prophets ever stopped to consider that there’s a chance that it just might be not permanent? or that, dunno, the writers might actually be able to do something good with that concept, like they have proven their ability to do so before?
 
stop pissing your pants

If the show just turns shitty.

They’d have to kill off Applejack or make Trixie into a mane character.
