With its finger-on-the-pulse tagline, “Welcome to the anti-social network” and respectable credentials, Chatroom is an intriguing prospect. It’s based on an acclaimed stage play, directed by the visionary Hideo Nakata (Ringu, Dark Water), with a script by Enda Walsh (Hunger) and populated by a cast of bright young things including Aaron Johnson and Imogen Poots. However, this cyber-thriller offers precious few thrills and is hampered cringingly by an absolute lack of authenticity. It is, as its title and tagline suggest, an exploration of the chatroom phenomenon, focusing on five teenagers as they forge friendships in cyberspace; yet it is so hopelessly out of touch with the generation it purports to portray that, although the overarching premise rings (fairly) true, it is for the most part excruciatingly inaccurate.
