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.
If we are doing just critic score, The Boondock Saints. I've lost count of how many times I have seen it.
I already loved the movie, but I went to a Q&A with Sean Patrick Flanery. Norman Reedus was held up, so missed the Q&A and only did pictures later on. I was disappointed at first, but it ended up being one of the most hilarious and entertaining 1-2 hours I've ever seen. I wish I could remember specific details, but I do remember telling him it was an amazing Q&A when I got my pic with them.
