Inspired by the linked XKCD. Using 60% instead of 50% because that's an easy filter to apply on rottentomatoes.
I'll go first: I think "Sherlock Holmes: A game of Shadows" was awesome, from the plot to the characters ,and especially how they used screen-play to highlight how Sherlocks head works in these absurd ways.
The critic vs audience score divide is pretty telling for some movies. Ant-Man: Quantumania and both Venom movies come to mind as movies that were critically panned but had pretty high audience score. They're nothing spectacular but still dumb fun movies.
