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.
House of 1000 corpses, 21% on rotten tomatoes and a perfect 10/10 for me, the soundtrack and the visuals are incredible, with super fun villains to match.
