Keep Watching review – tech dystopia becomes a song and dance

New Diorama, London
Jesse Fox's play about the perils of surveillance is at its best when observing the bond between sparring siblings

What makes technology scary are the unknowns: our inability to control it, our data taken without informed consent, being watched when we aren't aware. Jesse Fox's play attempts to explore the dangers of tech, but misses the dread and drama.

Exhausted A&E nurse Kat (Beatrice Scirocchi) walks straight into a data trap, flippantly handing control of her iPhone over to Jo (Luyanda Unati Lewis-Nyawo), a stranger and surveillance expert. Here, she says, have it all! Monitor my every move! What a surprise when - shock horror - being watched isn't as comforting as she imagined.
