But film director Martin Scorsese isn't such a fan. In an essay for Harper's magazine, he's warned that cinema is being "devalued... demeaned and reduced" by being thrown under the umbrella term "content". He specifically criticised a lack of curation on streaming platforms, saying algorithms, which provide recommendations based on individual or collective viewing habits, are damaging the art form and "treat the viewer as a consumer and nothing else".
