Disturbia is a nice little mystery thriller that takes a wrong turn on the way to its climax and morphs into a slasher movie. This abrupt change in tone is as jarring as it is unwelcome and transforms what could have been an effectively tense conclusion into something so over-the-top that it's almost laughable. During its best moments, Disturbia doesn't have the material to be memorable, but it is watchable and the subject matter holds an undeniable fascination. But the filmmakers' belief that modern audiences will only respond to noisy, inarticulate endings dooms this movie to a last act that devalues, rather than elevates, it.
