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 wish that movie didn't spoil itself with its opening scene. They make sure you understand you're seeing the post-story world first, then jump back to actually tell it. Makes me wonder what it would have been like skipping past that bit, not knowing how it had to end.
