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.
Valerian and the City of a Thousand Planets - The opening sequence is pretty amazing actually.
Sex Drive (esp the directors cut)
This is harder than I thought it would be. I was also surprised at the ratings for Mars Attacks and Sex Drive. Mars Attacks is a legit great movie but admittedly very odd. Sex Drive is just stupid fun.. Kinda peak teen sex comedy. Not perfect but funny in it's own way.
Sex Drive Directors cut is ridiculous. Just plain ridiculous. I love the character of Ian's older brother when he realizes his Judge has been taken and he's visualizing his younger brother driving around in it eating a jelly donut LOL. Also when he's just sitting in his driveway depressed that his cars been taken and is wearing his motorcycle helmet for no reason.
And in the end, the big twist about Lance (was this his bros name?) at his family's Christmas.
Mars Attacks, like most of the options I can l think of, is not post 2000 so it fails requirement 2. I think I'm going to throw out Bulletproof Monk as my unpopular like.
