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 know it doesn't meet the "post 2000's" rule, but I saw it for the first time a couple years ago, so I think it still counts. I don't think it was a very good Mario movie since it took A LOT of creative liberties with the source material (tbf, there wasn't a lot to work with in 1993), but as its own thing, I enjoyed it for what it was. Definitely expected a lot worse when going into it.
