I have nothing against MLP, I find it cute haha, but TWD, even though it may not teach you much, it's a good show. Like really interesting n all :)

The personalities are generic and relatable. if you want to see something the same effect as My Little Pony go and check out Pretty Cure. Both series are based around characters have generic personalities and go on adventures and things like that. Despite my little pony being tons more popular, the shows are comparing aren't at all alike. You would want to compare My Little Pony to other flash animated shows or shows that involve characters like these. I can't say that I've watched my little pony but from my observations this is what I think
