That's because it was executed in a disastrous method that completely missed the point about why MLP is so good in the first place.
I thought Faust had always promised there would be NO human characters interacting with the ponies from the very start. So haven't fans always been against the idea of human characters? I know I was ._. Of course, like I said earlier, it's not technically showing humans walking around in Equestria. Like an alternate universe loophole really.
Alternate Universe 101 all bets are off. I'm used to AU scenarios. I do occasionally take part of shows like doctor who after all. Compared to the Daleks or universes where all the heroes and villains have swapped roles, EqG is tame. I can handle this just fine.
I've only seen alternate universes when it comes to either superheroes or video games I don't really have any interest or desire to watch Doctor Who.
Oh poor Lyra. Wait a minute, Vinyl Scratch is in the human world so why would she be here with the others? And why are the rest of the other mane 6 here? I'm just over-analyzing this, but I get the point. Maybe Lyra will be in the movie, who knows? As the anthropology teacher?
That image ANGERS ME. AAAAAARGHH. STUPID BACKGROUND PONIES!!! I want to just Hulk Smash™ everything!!
Those are just things that fans came up with since we don't really know anything about their real personalities in the show.
