“Vicious” (*1/2 out of four) was a viciously dull time-waster about a young woman (Dakota Fanning) who is imprisoned in a house and has to fight for her existence against a sinister force but that finds that her mental health begins to fragment (and yours will too by the end). One-note movie in which even the one note is pretty flat; Fanning is good under the circumstances but is unable to enliven the tired material. Yet another movie which might have worked better as a one-character play. A disappointment from director Bryan Bertino who previously directed 2008’s “The Strangers.”
