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.
The only movie I’ve seen that get more laughs over the premise during the preview was the GI Joe movie. People were really into it as the trailer played and then the title came up and the whole theater room burst out laughing.
