There's a case for just watching TV and movies and not learning anything about how the sausage is made, but then you'd lose out on little pleasures like noticing that a recurring actor just got promoted to the end of the opening credits ("And Teryl Rothery as Dr. Frasier" in #Stargate). (When I saw Avengers: Infinity War, the audience actually laughed at the "And Chris Pratt" credit like it was a joke or afterthought instead of a significant place in the pecking order with a cast that stacked.)
