New York Times:
Acting, for the moment at least, seems almost entirely beyond her…she pouts, slouches, storms in and out of rooms and occasionally cracks a snaggle-toothed smile, but most of the time she seems to be mugging for the camera, play-acting rather than exploring the motives and feelings of her character.New York Post:

Cyrus, alas, hasn't yet learned not to act with her eyebrows and overbite.Poor Miley. Now might be a good time for those acting lessons.
