Aarkkariyam review: A Hitchcock-like mystery thriller with a shocking twist the film successfully manages to impress, engage and shock with its one unexpected twist hitting hard, strongly reminding you of the tactics of maestro Alfred Hitchcock Set in the initial days of the first nationwide lockdown last year, Aarkkariyam (meaning 'who knows') is a distinctive attempt that refuses to follow the set format of a crime mystery thriller. It neither has that fast-paced, exciting narrative nor many twists and turns thrown at every 10 minutes to keep you glued to the seats. Yet, the film successfully manages to impress, engage and shock with its one unexpected twist hitting hard, strongly reminding you of the tactics of maestro Alfred Hitchcock.
