If anything, media made for a malleable audience with low critical-thinking skills should be held to a higher standard, not lower. I still remember how much I loved The Hobbit as a child. Even at the age kids don't remember stuff, you still set the groundwork for the rest of their lives. The argument insults kids and betrays the speaker's low opinion of them.
It's a shame discourse is still stuck where it was when SWSH came out. I hope the fandom can move forward some day and accept that a billion-dollar franchise isn't immune from critique.
It haunts my dreams.
