Maybe someone here remembers the name but I read a short SciFi story about someone who edited a mediocre movie into an amazing movie, posted it online, got tons of hits, was offered a job by the movie company. When she arrived it turned out they wanted her to be part of an audience of people with good taste. Some AI made the movies, they'd play them to the audience with tracking equipment on their heads. The AI would use the info to adjust the movie. Their memories of having watched the movie would then be erased. Repeat several thousand times until all readings are high. Release movie.
