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.
Mine is Stealth from 2005. Not high art by any means, but a fun action movie with some pretty cool special effects. Also written by the guy who wrote Big Trouble in Little China and directed The Adventures of Buckaroo Banzai Across the Eighth Dimension so bonus there.
