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 tuned into Sucker Punch while flipping through tv channels one day. It was in the middle, never heard of the movie before, and there was this badass chick killing zombie Nazis with a sword! For like 10 minutes! No context! It was amazing!
