Nightmare Before Christmas is so well done that it's artistic achievement is overlooked. Indeed, Tim Burton's whole contribution to the arts is often glossed over due to his mainstream success. I was glad to see his exhibit at the MoMA back in 2010 - it really brought the level of discipline, tenacity, creativity and whimsy in his work into sharp focus. It was also nice in the way it showed some of his lesser known works and even a few missteps (his Superman costume concept - Edward Scissorhands meets steroids? AWFUL.) But the aesthetic he has created (with huge nods towards Gorey and his ilk) has become iconic across all mediums.
And speaking of achievement in the medium, the BBC Sherlock series is awesome! Steven Moffat is a bloody writing phenom - his Doctor Who's rock, with far more cohesiveness and story structure than Russell T. Davis was ever able to muster, and on top of that he creates this fabulous re-imagining of the Sherlock Holmes stories, which manage to both pay homage to Doyle's original masterpieces and do something new, original and suspenseful with the stories! SO much better than the Guy Richie nonsense. Even Hounds of Baskerville, which is probably my least favorite of the 5 episodes/movies thus far, is excellent.
