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, Robot - extremely disappointed that it didn't follow the books, but I've watched it several times and if you pretend it came out under a different title it's a good robot movie.
