A funny and touching Kristen Wiig walks an acting tightrope in this dark comedy about a woman with Borderline Personality Disorder who quits her meds and buys her own TV talk show after winning an $86million lottery jackpot.

Her show’s only subject, Wiig’s Alice Klieg uses her platform to rake over decades-old grievances, offer half-baked nutritional advice and even neuter her pet dogs live on air.

Welcome to Me doesn’t purport to be a serious study of mental illness – and it doesn’t make the most of its superb supporting cast, which includes James Marsden, Wes Bentley, Joan Cusack, Jennifer Jason Leigh and Tim Robbins – but its satirical jabs at car-crash TV and the cults of vacant celebrity and extreme oversharing are timely and welcome.
