The message director Bryan Bertino seems to be implying in The Strangers is not to misuse technology; doing so can get you killed. Two misused cell phones, one misused house phone, and a misused car and ham radio later, he clearly illustrates why in this latest iteration of the home-invading stalker movie. With similarities to 2006's European Them, Bertino's masked assailants lay siege to the desolate home and psyches of an already distraught couple, entering the premises at will and often standing quietly in the background watching their freaked-out victims Kristen (Liv Tyler) and James (Scott Speedman).

After his marriage proposal doesn't go the way he anticipated it would, James and Kristen head to his family's vacation house at four a.m. in the morning. With red rose petals strewn across the bathtub and bed, and a bottle of champaign less chilled than the soured marriage proposal, both try to reconcile the awkwardness by getting frisky instead. Of course, as you and I know, any hint of sex in a horror film spells trouble with a capital T. Right on que, a nerve-rattling pounding on the front door ends their reconciliation. Outside, a Squeaky Fromme-voiced girl, her face hidden in the darkness created by an unscrewed porch light, is looking for someone. Maybe it's me, but how can James not get a clue even when he screws the porch light back in after the girl goes away? Clueless victims in horror films make matters much worse, as you and I also know.

An empty pack of cigarettes sends him driving to the corner store for a refill, but the corner store is miles away, leaving Kristen all alone. Let's recap, shall we? A really creepy girl shows up at the front door asking--in a very creepy voice-- if some guy they don't know is home. Oddly enough, the porch light is unscrewed so her features are hidden in darkness. Oh, and let's not forget the incessant and really, really loud pounding that preceded her appearance: a pounding such a diminutive girl could not have possibly done on her own. Do you see where I'm going with this? apparently James doesn't. Maybe Kristen is right in not marrying such a dope.

While he's away, little squeaky comes back, more annoying and creepy than before, with more threatening pounding on the front door. Bertino adds a subtle shifting of the camera, right to left, left to right, as it focuses on the unsettled Kristen, reflecting her growing distress. Then the misuse of technology begins.

Instead of calling the police, Kristen calls James--you know, the dope who left her alone in the first place for an expensive pack of cigarettes. Oops, should have charged that cell phone. She plugs it in and goes for the house phone instead. Not much luck with that either. Gee, I wonder why? Technology can be such a bother when making a horror movie. Isolation is essential when creating the right mood and increasing helplessness. You can't have good horror if potential victims can make quick phone calls for help, or jump in cars and drive away from trouble. Better to make sure they're remiss in using all that life-saving, help-bringing, techno-crap; best to eliminate it right away, leaving them powerless. Dead batteries and poor cellular service are two ways to squelch this cell phone empowerment dilemma. Bertino uses them and more in nice, too-easy, techno-swipes enabled through poor decisions, as the strangers silently hover, surprisingly close, in the background, taking full advantage of James and Kristen's shattered composure and wilting thought processes.
