I reckon its conditioning more than a greater capacity for analysis. Adults have been used to certain on-screen representations all their life, until recently.kids can have opinions and thats fine, some of them precocious. but generally theyre opinions are still very nascent, theyre still in their formative years of thought, beliefs, understandings, experiences. why is it that only adults have an issue with this? because its a broad meaty topic and adults can analyze and incorporate other aspects of life as analogies.
Kids don't carry that conditioning so they don't see any issue.
