This summer has seen some truly atrocious film tie-ins - Spider-Man 3, Pirates of the Caribbean 3 - but Transformers is the laziest, most cynical cash-in of the lot. The action is simple, but not in a good way. Mostly it involves tedious pursuit and pummel missions set in a surprisingly ugly open city. The scenery is destructible, and there is some initial entertainment to be had stomping away at a house or car. But any joy is short-lived, extinguished by the nausea-inducing camera and repetitive gameplay. Even simple actions like locking on to a target or object are infuriatingly fiddly. Bugs aplenty - thrill as your robot gets stuck in scenery! - just add to the shoddy unfinished feel. You don't expect deep narrative tension from a game based around giant robots but Transformers is both shallow and dull. On the upside, the Transformers themselves are well animated, which is the only positive to take from this gaming disaster.
