Danny Boyle’s Trainspotting (B) is a veritable steam engine of a film showcasing the life of junkies from the other side of the tracks. Ewan McGregor charges onto the scene in a star-making performance, and Boyle’s grim, swirling visual odyssey gives viewers a one-way ticket to the human abyss. There’s a whole lot of surreal locomotion as the film alternates from comedy to surreal drama, all in an original, efficient tale.
