I have to say that I wasn't really sure about this, it seemed to be lacking pretty much anything, plot, acting, competent dialogue, anything that you really look for in a film. Safe to say that I wasn't really impressed by it.
Denzel Washington plays Walter Garber, a controller of the subway when one of the trains is high-jacked by Ryder (John Travolta) and other. Unsurprisingly the 'others' don't take much part in the proceedings, serving as canon fodder and people to be ordered about by Travolta. In fact, Washington and Travolta are really the only characters in the entire film, everyone else is just plot and space filling, allowing for the fact that it would be difficult to have an hour and a half (and believe me, it feels longer) film with only two people in it.
Ryder and others hi-jack a subway train and demand $10 million within the hour or they'll start killing hostages, and yes the hostages include a mother a son, a young man with a pretty girlfriend who is elsewhere, an idiot business man and a hero, and all play their parts just as you would expect them to.
Before they realise that a hi-jack has happened, and instead think that there has been a malfunction on the train Walter Garber tries to contact the driver, thus bringing himself to the attention to Ryder and thus becoming that only man that Ryder will deal with.
As money is rushed across the city (by quite possibly the most incompetent police escort ever seen) Walter Garber is given a crash course in hostage negotiation by the only other character in the film who has more than five lines to himself, the real police hostage negotiation that Ryder refuses to deal with.
Ryder then declares that the money must be delivered to him by Walter Garber and then Garber is pulled in to the events while he and 'others' try to escape with the money. So, how will it end? See if you can work it out?
There's nothing new or interesting in the script, it's all very predictable, and the script is incredibly uninspired.
As it's probably apparent I really wasn't impressed by it, nothing really stands out in my mind as a positive point about it.
