I have to say i was afraid about the movie. I mean when you spent your whole year writing codes for university to watch a movie with that name is like uni following you everywhere.
But it was good movie anyway. Full of excitement, action and anxiety. It actually follows 2 storylines. One where Colter tries to find the bomber in the train and one where tries to understand what really goes on with this mission out of the simulation. And both of them have kept my interest up until the end. You are getting small hints each time and you try to find what's up.
Unfortunately, i found the bomber at the first 3 mins of the movie but still i was nervous like hell. Especially about the other storyline.
The special effects are non existent so your attention is at the acting and story. I think everyone did a really great job, especially when they had to play the same scene over 10 times and each time to be different than the previous. Especially, Jake Gyllenhaal did good with changing his emotions in every scene and how lost felt out of the experiment. The only actor who made feel like he was just saying some lines was the head scientist. And even if Michelle Monaghan is supposed to be the hottie of the film, Vera Farmiga was simply perfect!
Source Code is a nice one time watch sci fi thriller which doesn't tires you with unnecessary info but gets from the first moment into the main plot and keeps you there til the end.
