Steven Moffat is in charge of both Doctor Who and Sherlock, two of the BBC’s biggest current exports (along with Downton Abbey). Unsurprisingly, there are many fans of both who have been dying for a crossover — Wholock, if you will. While Moffat thinks such a move would ruin Sherlock‘s setting (and I’m inclined to agree), that doesn’t mean it wouldn’t be awesome to see. That’s why this fanmade crossover is so great. There are minor flaws here and there, but for the most part, the two series mesh pretty well thanks to some clever compositing. it’s pretty cool to see Sherlock enter the TARDIS after years of searching for information on the mysterious Doctor and go off on an adventure. It’s just a shame that in becoming a companion, Sherlock is leaving behind his own companion.
