These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Fetish Retardant: Those ballerina costumes? The ones that are heavily sexualized? We get to see a preteen girl in one, whose dance is already way too mature for someone her age. Thanks, but no thanks.
Growing the Beard: Either the second season, or third, or both, stepped up the game. The third season made good on it's generically vague hints of a Myth Arc and has more complex character building in its episodes, rather than the former mindless "action".
