There's this particular scene that caught my attention readily where Sherlock and John were inside the Planetarium and there in the shadow was the oscillating Nosferatu-like figure of the Golem. I was sort of expecting Max Schreck's face. It felt like an homage to FW Murnau's fantastic oeuvre. Well, I applaud not only this one scene, of course, because there are many! Brilliant! Cannot wait for the Season 3!
