“The complete lack of preparation of that death makes it even worse,” says Zack Handlen. "Very little in Ragnarok (http://forums.previously.tv/topic/41664-s03e18-ragnarok/?view=getnewpost) felt like it was something that had to happen, and that makes for a series of random events that can’t really sustain the weight they’re intended to carry. The only explanation I can think of for this nonsense is the already mentioned theory that this is supposed to be some kind of unofficial series finale. But even by that metric it fails. I can’t imagine any fan of the show watching this and being happy how things turned out.” PLUS: Fans express frustration (http://jezebel.com/another-fantasy-tv-series-makes-a-point-about-who-is-ex-1770045071) over losing such a key character, and Sleepy Hollow boss says "you've got to find ways to evolve shows."
