Anna Campion, the sister of Jane Campion (“The Piano”), makes her directorial debut with this British drama about a group of young people preparing to embark on their adult lives. The group holes up in a deserted mansion making a horror film during a weekend that culminates in a tragic acid trip.
Using an unnervingly edgy style, the film effectively conveys a generation faced with a harsh, complex world. Also stars Thandie Newton. Rated R.
