Sadly, another way Sherlock is like Christmas is that we get like one episode of it per year, on average. That's why, if the wait ever becomes too much for you, you could try checking out CBS's Elementary, like I almost didn't. I mean, a modern retelling of Sherlock Holmes set in New York with a female Watson? So CBS just remade Sherlock but with a couple that straight people can masturbate to? Actually, no.
But also YES.
While I still love Sherlock, I'm now a bigger fan of Elementary. For one, the former has like 10 episodes out, in contrast to the latter's 100+. It's not a question of mere quantity, though. Because the adventures of Barcelona Cuckooclock come out so infrequently, it feels like each episode has to be bigger, darker, and more complex than the last one. The first episode was about a series of mass poisonings. The third one is about blackmailers putting people in explosive vests. The last one will probably be about Bastardneck Crumbcake fighting Satan in the center of the earth.
Elementary, on the other hand, can take its time and focus on smaller cases like home invasions, overdoses, hit-and-runs ...
Shirt thefts, apparently.
