Audiences haven't rejected sequels or reboots. They've rejected bad movies and rewarded quality. Aladdin is an easy movie to look towards when judging a movie that was rebooted and has been extremely successful. Toy Story 4 has been less successful than Disney wanted, but it's still doing big business. John Wick 3 has seen huge numbers for the small amount of money spent on the film. Far From Home has opened extremely strong and already over $500M WW.
It's movies like MIB: International, Dark Phoenix, SLoP2, Godzilla: KotM, Shaft, Child's Play, etc. All have had poor RT Scores and the movie going public probably got pretty picky after spending a lot of money to see Endgame multiple times. The public rewarded quality this summer and it's not often we can say that, so i'm actually proud to see this development.
