If Split/Second: Velocity was a song, it would be “Boom Boom Pow”. If it was a film, it would be a Fast and the Furious title. Shiny, fast-paced and (at least at first) shallow, its premise is that this is all a high-octane, violent vehicular reality show where obstacles and explosions are thrown in front of any competitor crazy enough to take part. It seems a bit high concept for an arcade racer but it works, letting the motoring madness run riot.
