First-time helmer Bryan Bertino is beholden to genre quota, skidding the relationship of pretty young couple Kristen and James (played by Liv Tyler and Scott Speedman) before subjecting them to an after-dark home invasion. But Bertino offers no profound rationale for why Kristen refuses James's marriage proposal; like the shadowy stranger that comes knocking at their door (eerily asking, "Is Tamara home?"), it's something that just happens.

What's up with the bemasked ghoulies of the film's title? Why all the door-slamming? Who's Tamara!?! Plying an old-school artistry that begins with a creepy montage of bumblefuck houses and holds up almost without fail until the strangers offer a creepy nonjustification for their transgressions, analog-man Bertino teases with the unknown until he has left no pimple ungoosed. Sometimes avoiding the synapse-raping bad habits of splat packers Eli Roth and Alexandre Aja is its own reward; doing so without also submitting to Michael Haneke-style hand-slapping is nearly monumental.
