Both TV and Cinema have become obsolete. Cable TV and streaming has changed the way entertainment is delivered.All I watch TV anymore is for local news and weather. The rest of it is pretty much crap.
The content has also changed because it is possible to target entertainment to specific audiences as never before. However, within a given genre, say action adventure which appeals to the pollical left and right, young and old then there will be content conflicts. Maybe sometime in the future we will be able to select a title and and select content changes to fit beliefs and desires of various groups. For example, for a selected move, make it G, PG or R, include or exclude certain political content. This may be possible when CGI dominates entertainment.
