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.
...howard the duck is my standard-bearer for an unconditionally good movie which gets everything right, but it only rates 14% with critics and 38% with audiences: i'm absolutely convinced that a minority of those ratings are from folks who just didn't get it at the time and the majority are folks who've since dogpiled-on because they believe they're supposed think it's bad...
...it's not-at-all a bad movie; it's solidly entertaining from start to finish, masterfully-produced, and i love it more every time i watch it...
It's funny, I've read through this whole topic, and agree with every movie everyone has suggested.
But when it comes to Howard Duck I had to draw the line there, it's a horrible movie, but I'm laughing at myself for thinking it's a horrible movie, as all the other movies that most people think were bad I actually liked.
So there's got to be something about that movie that was just not entertaining for watch for me, vs. the others.
