I believe they're in the phase of "role model" where they set the example and we learn from it. I do not think it's bad since they're probably the few things in this world that teach me good morals. I can happily say I've learned quite a bit about friendship and how to act because of the Main Six. If it was on a more toned down scale I think it would appeal less to younger audiences and I think Hasbro want to keep it appealing to this "younger audience". You could watch a drama on the tv if you want a more relatable main character with a much more real to life setting. But for the MLP universe I think it's perfect the way things are, over the top fun.
