Supernatural, Doctor Who, and Sherlock: Three very popular shows that have formed into one fandom because one is rarely watched without eventually being dragged into the other two universes. But what makes these three, very different shows, so appealing to viewers? Why this combination of Sci-Fi, Crime Drama, and Horror? The appeal could come from the witty dialogue, the action based plot lines, or maybe the great many ship-able characters that fans fall in love with.
I think it would be very curious to analyze why these three fandoms in particular merge into one -- since there are a TON of massive and very interactive fandoms out there. Also, I think something not worthy with Doctor Who is the fact that inbetween seasons they had active "web series" to help fill in the blanks of what was happening. This kind of world building helps to solidify the universe and gives fans much more material to play with. – Pamela Maria7 years ago
