This is the red-band trailer for Hemlock Grove, a new Netflix original that is now available to stream through the subscription-based television service.

The “red-band” element means the footage is for mature audiences only, so don’t watch if you’re faint of heart or not into a little gore.

Hemlock Grove is a supernatural thriller directed by Eli Roth, best known for the stomach-turning Hostel movies. Werewolves are the order of the day here, and as Netflix shows aren’t classified, the action gets pretty nasty.

As with all Netflix shows, Hemlock Grove is presented in episodic form but whole series are released at the same time, so the first season is now available to stream Twilight fans should flock to it.
