Watch three irascible women screaming at each other: Anthropology, at Hampstead Theatre, reviewed

Anthropology is a drama about artificial intelligence that starts as an ultra-gloomy soap opera. A suicidal lesbian, Merril, speaks on the phone to her kid sister, Angie, and they discuss Merril’s beautiful ex-girlfriend. After ten minutes, we learn that Angie’s voice belongs to a robot, Digital Angie, created by Merril to replicate the real Angie who vanished a year earlier in unexplained circumstances.
