The only reason that I sought this movie out was due to Elizabeth Henstridge, who plays one of the main characters in Marvel's Agents of S.H.I.E.L.D, a show I rather enjoy. And as it turns out, aside from Henstridge, this movie doesn't have much going for it. Dramatizing the events of the murder of Sharon Tate and company (purely hinted at until the end), Wolves at the Door is almost utterly run-of-the-mill. If you've seen Ils (2006) or The Strangers (2008), or hell, even The Purge (2013), you've seen a more enthralling and tense movie than this one.
Adam Campbell (Wojciech) has some decent scenes, and if you like the ascetic of someone dragging a sledgehammer across the ground, well, Wolves at the Door has that also. But aside from Elizabeth Henstridge, who does a decent job despite the shallow script, the best I can say is that occasionally good 60's songs play, such as 'She's Not There' by The Zombies and 'Lil' Red Riding Hood' by Sam the Sham and the Pharaohs. There's nothing else though - this movie is otherwise empty. And while I wasn't fond of it that first time I saw it, I'm even less fond of it now. Not much here to recommend, folks.
