The show is indeed for little kids maybe even 10 to 12 year olds, BUT that's on the surface. The ingenuity, the writing, the appealing stylization (the cute anime like eyes), continuity, and oh my gosh the personality and voices of the ponies are superb. If you are a nerdy kind of teenager or adult then boy are you in for a real treat.
It's the best cartoon this 24 year old guy has seen in a very long time. It's practically untouchable in my eyes, I haven seen a cartoon with this much effort and love put into it.
People who grew up watching cartoons would likely say it's for anyone. If you're asking who the specific target audience is though it's for small girls.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
