Beneath the leather and diesel, a heavy whiff of A-lister indulgence comes off this Brad Pitt-produced doc profiling the young generation of bikers who've dethroned reigning Moto GP champ Valentino Rossi.
Director Mark Neale ekes out traces of personality – the goofy Marco Simoncelli is such a vital pit-lane presence that events at the 2011 Malaysian GP catch everyone out – but any drama is limited to the track: its grip depends entirely on your interest in watching men leaning at high speed.
A lax edit offers diehards two-plus hours of that, but nobody's likely to mistake Pitt's narration ("Crashing hurts … it wrecks your bike") for expert analysis.
