It's got a lot to uphold being the successor to Friendship is Magic. The animation for the series was never going to be as pretty as the movie, it's not the best but it's also not terrible.
There are a few aspects of the series which bother me, particularly the over-use of mobile phones by Pipp. (I feel like this will be a part of her character development however). A few of the songs have felt a forced/unnecessary and there have been moments where it has felt very childish.
However, it IS a kids show. The characters are cute and likable. I'm curious to see where the story goes and there have been a few moments that have given me that warm fuzzy feeling. So far, I have really enjoyed the new series. I'm excited to see what the future holds for My Little Pony.
