Claustrophobic and brightly colored, this tightly wound psychological thriller is constantly pulling the rug out from under the viewer, mostly due to the tense, explosive performances of its two main charactersThe tale opens with a coffee shop rendezvous between 14-year-old Haley (the fantastic Ellen Page) and 32-year-old fashion photographer Jeff (Patrick Wilson), who have previously met only online in a chat roomDespite his questionable enthusiasm at meeting a girl half his age, Jeff comes off as slightly awkward and shy; rather, it's Haley who is unnervingly forthright in her flirtationShe suggests that they go back to his place, he complies, and, once there, Haley seductively convinces him to take pictures of herShe exhibits a beguiling mixture of innocence and precocious sexuality, but before anything happens between them, Jeff passes out under the influence of the drugs she's slipped himWhen he wakes up, Haley drops her innocent demeanor and begins to undertake a meticulously planned game of retribution against her captive pedophileShe hacks into his computer and ransacks his house while he watches helplessly, and she ultimately raises the ante with a surgical procedure sure to make audiences squirmThe exact nature of Jeff's guilt remains nebulous, however, creating an intriguing uncertainty surrounding Haley's own mental state, and just how psychotic she might beExpectations are continuously thwarted as the two characters--neither of whom is terribly sympathetic--enact a psychological and physical game of cat and mouse that is as fascinating to watch as a train wreck.
