Well, I see what you mean, but children in the Barney/Sesame group (The two age groups do mix, around the latter of Barney's end) need that sweetness in their everyday life - Why not bring that over to the television they watch and the characters they'll emulate? It is quite obviously true that Sesame has the much bigger adult fanbase - Barney has one as well, but, it must be said, it's much smaller. But you see, I feel like this whole idea of trying to make shows for this age-group appeal to adults as well is rather silly - Yeah, patience will grow short in the adults, but that's just part of caring for children. As I said, I feel that this stress of appealing to adults takes away from the educational value. You brought up My Little Pony - I became a Brony when the second season was still running, but I was mostly watching Season 1 episodes first. When transitioning to Season 2, I certainly saw a much harder attempt to appeal to Bronies in that season, to the point that it seemed to be the main intention, rather than teaching friendship to the people the show was made for. I think around the time when television becomes an independant activity (I don't think it should until at least five years old), then trying to appeal to adults seems to be a worthwhile thing to do. But hey, this is all just my opinion. You're certainly welcome to yours, my friend.
