You know the pitch: There's a runaway train laden with chemicals that are both poisonous AND explosive. Denzel Washington and Chris Pine star so it must be up to them to stop it from careening off the tracks into a gas depot slap bang in the middle of a densely populated town. Fantastic? No, it's actually based-on-a-true-story! Will the runaway crash into the train laden with schoolchildren in the first half hour? Will the bit part actor succeed in halting it at minute 45? Will the big bad boss choose the wrong strategy in his attempt to stop it? Will our heroes disobey boss-man and put the brakes on the runaway? Pick the obvious answer to all these questions and you've got the plot! Cue shots of Chris Pine trying to reach his estranged wife while his walkie-talkie barks "Pick up the walkie-talkie, Will!" Cue lots of people in control rooms punching the air while mouthing "Go, Frank, go!". Cue loved-ones in bars staring at screens showing our heroes in mortal peril. This is Tony Scott so every shot MUST be tracking, zooming or vibrating; and that's before the action starts. Scott is a master of filming fast-moving metal objects but where is the tension supposed to come from when the resolution of each situation is so staggeringly obvious? Washington, Pine and Dawson are all a pleasure to watch but beyond them there's little to engage the interest if high-speed objects don't turn you on.
