Exhibition chess may well be called the Intellectual Olympics, but you'd be hard-pressed to find a game less beautiful. Attempt to master it and you'll find yourself transformed into either a persecution junkie, a Tyrannosaurus nerd or a paranoid head-wreck. Vikram Jayanti's sycophantic documentary goes emphatically for the victim angle, picking through the events of 1997 when Grand Master Garry Kasparov was thrashed by a "terrible faceless monster" - - IBM supercomputer Deep Blue.
Clearly Game Over fancies itself as a conspiracy thriller (Kasparov claims IBM cheated by using human players). But Jayanti fails to engage on nearly every level: his talking heads are droning geeks, evidence of IBM's scam is negligible and his psychological excavations are a scrape in the sand - - deadly for a film about such a dynamic, complex and corrupting mind game.
As a story, Kasparov's AI-versus-IQ battle still intrigues. As cinema, though, it's stalemate stuff that's only fit for BBC2 on a bad night. Shame.
