first of all, i love Denzel Washington, but this movie in one word .....horrible... Unstoppable is a drama about a runaway train carrying a cargo of toxic chemicals. Pits an engineer and his conductor in a race against time. They're chasing the runaway train in a separate locomotive and need to bring it under control before it derails on a curve and causes a toxic spill that will decimate a town - yes this story could be in five minute version, where guy get on the train and stop it, nothing more in this movie. action,drama and thriller- no,i haven't seen anything of these, only movie full of stupidity. sorry for that, but i've expected much more
