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.
Haha that film is fantastic, I think it's time for a rewatch!
Side note, The Man Who Knew Too Much is also a fantastic film (James Stewart and Doris Day, and yes they shoehorned her singing the song in to the film haha).
