Did you guess who was the ... *Spoilers!*
... werewolf?
From the start I was pretty sure that neither Jeanine (the inn owner) nor Emerson (the hunter) were the werewolf, and I was suspicious of Finn (the ranger). I thought he was a werewolf, but not the one who is killing people. At first I thought there is a just a regular, fully-human murderer among them; Then I thought there is another werewolf other than Finn; and finally I came to think that maybe there was no werewolf after all. But I was wrong!
In short, although the film didn't provide enough clues for me to be suspicious of all characters, I still enjoyed the mystery, because it made me doubt whether there was really a werewolf among them.
But did you guess who was the werewolf? At what point did you guess it? Do you think the mystery was well-handled?
