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.
I also thought horror would be an easy genre for this, but after scrolling through the last ~50 movies in my watchlist I only managed to find a single one that matched the description: Dark Skies (2013).
