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.
For people with Letterboxd I found some lists where it’s easier to compare with your watched movies (by hovering):
https://letterboxd.com/23warnecol/list/good-movies-with-bad-rotten-tomatoes-scores/
https://letterboxd.com/poisonivies/list/good-ratings-on-letterboxd-bad-ratings-on/
https://letterboxd.com/pakejanek/list/good-movies-with-bad-rotten-tomatoes-scores/
Now personally I’ve watched very few of the movies in those lists and almost all of those I’ve given very bad scores or have abstained to. The best one was 3/5 for Star Wars Episode I, which I though was fine.
