Something that bothered me about Friendship Games (Spoilers)

So a third movie came up with the characters of the human world, ending with a climax that reflects the final act of the first movie with Human!Twilight becoming a power-crazed dark angel, and Sunset Shimmer becoming a fire angel to stop her... but both of them suddenly have horns...

Let me tell you why this bothers me:

The producers in these movies had to make one big decision when making the movie: Keep the characters recognizable for the target demographic, or making the characters look realistic?

Of course, since the target demographic are children and everybody knows that children are dumb, they went with the first option. Thus, we had a "human world" filled with people with pastel colored skin and hair and with names that you wouldn't call your child unless you were Mandark's parents (Dexter's Laboratory).

Now these characters are virtually the same, except that now they all come from the same cookie-cutter, instead of having three. Then, the movies went a step further and made the main 6 plus Sunset be able to "Pony-up," changing their human ears to pony ears, having their hair grow longer and in the case of the three characters that we know have wings in the Pony world suddenly grow wings too.

But what happened with the magic users? Do they grow a horn on their forehead? NOPE! Somebody during production pussied out and didn't went all the way in with the ponyfication.

You have technicolor skin and hair; You have Pony Names instead of normal, human names; You gave seven characters the power to turn into Anthro-ponies. You gave three of these seven characters WINGS when they turn.

You went into great strides to make sure CHILDREN didn't get too confused at the pony characters turned human, yet you don't have the BALLS to have the characters that are UNICORNS grow a HORN when they pony-up?

FAIL!

And now, in the third movie of these series, after two movies where neither Rarity, Twilight or Sunset had a horn appear on their foreheads, you suddenly decide to have Sunset have a horn and Human!Twilight, who had nothing to do with the previous two movies, also have a horn?

ULTRA FAIL!!!!!

This shows one enormous lack of thought, since they weren't commited enough to go all the way with the pony-traits, and then a even larger lack of commitment by not remaining consistent about this detail.

Consistency is something that really bothers me. It is the reason I dislike the Harry Potter Films (Oh look, Harry's Patronus can take the form of a buck ONLY ONCE IN THE ENTIRE SERIES!). If you can't bother to make your work consistent, then I can't take it seriously.

Sorry. It just bothers me a lot.
