To a degree Dave but that is also offset by the modern trend for not giving press showings or doing them far closer to release date. 30 years ago a premier would be a good 3-4 weeks before a general release. Done specifically so the reviews could get out there and be consumed in a slower cycle, with the hope of course they will be good because nobody goes out with the intention of making a bad film. I may be a bit older and uglier but a bad NY Times review pretty much sunk a movie in 1987.
I really don’t find RT that different or reductive. I use it occasionally but my main source of critical feedback is the Kermode and Mayo show which has a single critic but also a lot of feedback and counter arguments from listeners. In the end they generally came to the conclusion that Wonder Woman (92%) and Dunkirk (93%) were very good and Dark Tower (16%) and The Emoji Movie (8%) weren’t.
If you magically erased RT and replaced it with a critic and fan listeners, nothing would change.
After having never seen any of the Mad Max films and having no real interest in them the 100% initial score for Mad Max: Fury Road was solely responsible for me getting a ticket and seeing it in the cinema and I thought it was the film of the year.
