> Content is graded on both instant appeal (e.g. rotten tomatoes "popcornmeter") and artistic appeal (e.g. rotten tomatoes "tomatometer").

I understand the distinction, but I don’t find the examples compelling. The difference between the popcorn and tomato meters, as I understand it, is just the source. The latter are critics’ opinions while the former are “regular people” opinions. Professional critics may have some concern for the artistic value of a movie, but their job is to help you decide “should you spend your time with this” and the entertainment value is a primary consideration. Furthermore, a critic can have early access and needs to write their review fast. An audience member, who has no such obligation, can let it ruminate and have their opinions evolve. In that sense, a critic’s opinion may be more influenced by initial appeal.
