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.
Was it as good as Not Another Teen Movie? No, probably not. But it still had some hilarious moments and lines. I especially enjoyed the long running jokes they kept sneaking in throughout the movie.
