Not really. Like stripper said, many of the messages of friendship the show teaches are common sense among adults. And friendship seems to be the only discussion-worthy concept the show stipulates. There is of course, loyalty, honesty, generosity, kindness and laughter, but these all coincide with friendship in MLP. The show doesn't really delve into any other lessons, it always leads back to friendship. Which is understandable and fine, but as a young adult, these lessons aren't really insightful or interesting; it's shit I already know.
