Flixster says its received about 5,000 individual reviews despite only playing at a maximum of 760 locations to date.

Flixsters overall inquiries into showtimes, information and tickets for Paranormal Activity grew by 36 this week on top of last weeks increase of 329. Its exceedingly rare for a movie to increase this much week over week, rather than see a decline, said Flixsters cofounder and CEO Joe Greenstein. Paranormal Activity is exactly the sort of phenomenon weve been anticipating a movie fueled not only by positive critical response, but by the buzz, feedback and wordofmouth excitement generated by moviegoers who get information and make decisions online, driven by what their friends and acquaintances say.Todays audiences say that online word of mouth has become one of the most important elements of their movie decisionmaking, and Paranormal Activity is certainly benefiting from that shift in behavior, said Amy Powell, senior vice president of Internet marketing at Paramount Pictures.
