Certainly sci-fi films require a certain amount of 'suspension of disbelief.' Say that we're told there is a parallel reality, I'm there. Say that a large ship can travel the speed of light, no problem. Say that the ship is going the speed of light in the WRONG direction ... big problem. And that's my problem with Source Code, an initially interesting premise that breaks down as utter stupidity.
How does Goodwin buy into this nonsense of this 8 minutes of dying man's (Sean) thoughts? Not going into the thoughts themselves but ... how does that premise move forward to actually finding the bomb? So what ... getting into Sean's dead or dying mind gets Colter moving things forward past what Sean knows about or dreams about (post-death)? No, no you say, that post-death thoughts only gave Colter access to the train and Colter's mind takes over from that? To what exactly? To go back in time? To a construct (post-death) that Sean can't create? Well, just while we're kidding ourselves let's say yes. So what part of a parallel reality aren't we already into and why wouldn't anybody over a fifth grader realize this?
Playing devil's advocate to my own idea, let's say Dr. Rutledge KNEW about the parallel reality and the 8 minutes scenario thingy is there so that BOTH the patient and his underlings stay thick as as brick? That would certainly support why he immediately kills all discussion about what Colter tries to share with him. After all, if that's not part of the story, then how did he come up with the 8 minute scenario? Pure stupidity from someone smart enough to get someone's mind into a parallel dimension? Please. That leaves the question as to why he would treat his own people that way and why anybody would be that gullible which is my BIG problem with the story ... it's smart people going at the speed of light in the wrong direction.
What exactly does Goodwin think Colter is going the SECOND time he goes into Sean's mind? If it's a 8 minute happening, why does it keep happening time and time again? Why does she think that any bombing that's also fact results in a scenario that keeps playing out? Knocking on Goodwin's forehead, hello ... anybody home? How do the underlings get hoodwinked into this 8 minutes of a stink bomb of a dead man's premise? Nobody around for the research stage? How is the parallel reality not a given? That's should be as certain as that Sean is completely fucked.
