> Didn't our parents also think our content was objectively inferior to theirs? I would personally agree with you but it may also be that we don't understand the new content well enough to properly value it.

I don't think there's any comparison. The parents could point at some mass production and decide it wasn't to their taste, but ultimately they lived in the same world. Our kids are watching amateur productions they find on YouTube. You can tell the production quality is lower from things like what the images look like, terrible planning, bad sound, and so on.
