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.
People don’t like it because it has nothing to do with the source material beyond some character names. It’s literally a random action script that had Asimov slapped on top of it just so the studio could legally claim to be using their movie rights. No relation to the book. Nothing at all like anything the original author himself would have ever written, to the point of being disrespectful to one of the greatest of the genre.
