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.
That's right, the prequel to the 1997 horror film Cube. Where people are trapped inside a cube that keeps killing them.
I feel like I'm cheating because it got some positive reviews, just not enough to even have a critic score. Audience score is in the 20's. I don't know why! It's a great follow up. Much better than the sequel, Hypercube. It gives us some much needed backstory on why the cubes exist and what their purpose is.
Sorry (because I guess it breaks the premise of your original post :-) ) but I totally agree - Going back to the gritty, less technical cube added so much and getting a look 'behind the scenes' was a great direction to go. Ohhh maybe I should watch Cube and Zero again!!
