The witches who speak as one were pretty lame, IMO. The ending was a bit contrived as well, although some of the acting on behalf of Mison and Lord Denethor, son of Ecthelion was pretty good. But that's reflective of their personal skill, not the skill put into the writing and presentation of the show.
Sleepy Hollow is likable, but ranks lowest on my current watchlist. I mainly watch it because it fills the gap between Almost Human and The Blacklist.
