"Content" is to series, movies and films what "grub" is to good food and fine dining. When creators say "content", they in a way degrade the quality of their own work (they should sell it as the equivalent of good food or fine dining, not as "grub"); when those that watch just call it "content" they probably don't have a very deep connection to it: So much better when the viewers come away from something and think of it as a story, and experience, a show, rather than "content".
