Messy, senseless, and even ugly at times; Source Code still rips. Jake Gyllenhaal is the perfect actor to build a film like this around, and he takes what otherwise may have been a forgettable action-sci-fi flick and instead instills the movie with the same frantic charisma he delivers in many of his signature roles. If this concept was brought to reality with a higher budget it might have left a larger mark in popular culture, but this hits the spot all the same for me.
