The show is intended for a much younger audience than us, I think the show has come along way is getting a lot better but that's your opinion. Remember this FIM isn't all to do with the show, its also to do with the friends you have made, the amazing art, music and fim fiction. If you think you are loosing interest then you need to get out there try different things, anime, gaming there is a lot of things I do outside the fandom, that keeps me interested in the fandom.
