Well, The Untamed easily has the biggest fandom:). I haven't watched it myself or read the web-novel it is based on, but a number of my friends are in the fandom one way or another (there are lots of live action RPGs, for intstance). As far as I can tell, it's a kind of media which is really fandom-generating (for a number of reasons, not just because of epic gay romance between the main characters), but is far from the masterpiece itself. Unlike, say, Nirvana in Fire, which is a wonderful example of TV as an art.
