Its not. Its more... 'family' oriented.
If you actually knew anything about FiM you would realize that the plot is quite interesting, the character development alone beats most shows on TV, episodes are incredibly engaging, etc.
Oh and its ADORABLE.
I really could go on all day about this. This is NOT your average children's show. Not even close.
Oh and the fans make it all the more enjoyable.
Seriously go watch some. Here:
