TheWrap‘s Dan Callahan is claiming that Kristen Stewart‘s portrayal as an angry, frustrated student in Tim Blake Nelson‘s Anesthesia, which screened last night at the Tribeca Film festival, is easily the strongest element. Stewart “has a nearly film-stopping monologue in a counselor’s office where she unloads all of her character’s rage and resentment about life. Nelson [lets] Stewart go as deep and as hard as she can into Sophie’s darkest feelings. She’s so despairing about what she sees around her that she has taken to burning herself with a curling iron in order to feel some control over her life, and Stewart makes this self-punishment seem gruelingly convincing and necessary.” Callahan adds that Stewart “is so tough and harsh here that she [actually] throws Anesthesia a bit off balance.”
