I might get hate for this but…
I hate all the Doctor Who/Sherlock/Supernatural crossovers. They don’t make any sense.
I can understand crossing over Sherlock and DW, since they both take place in the same areas and are written by the same person. So, crossovers of those make sense.
But I don’t get how Supernatural works it’s way in there. (Or, honestly, the appeal of the series.) There are very few instances the Doctor has been in America and all those times he’s been focused on something else. As for Sherlock, where the fuck does he fit it. It just doesn’t make sense. Also, what would the Doctor, even more Sherlock Holmes have anything to do with two pretty boy demon things? Seriously.
