"It's just a kids show!" isn't a valid argument to dismiss something's quality, but there are completely valid uses for it - for example "Why didn't Steven Universe murder his mother?" or "Why does the Pikachu movie have fart jokes?"
Not to mention that a lot of people who criticise the "just a kids' show" argument tend to also use the exact same mentality when people want to discuss preschool shows (that aren't about British trains or Australian dogs), even in a non-critical lens.
