Source Code is a fun movie - think Quantum Leap meets Groundhog Day. However, don't think about the story too much or holes will begin to appear. The best thing you can do is turn off your brain, appreciate the solid performances by Jake Gyllenhaal and Vera Farmiga and enjoy the ride.

Watching the movie leaves the viewer feeling frustrated and claustrophobic, just like the concept itself. The premise is that there exists a way to send someone back in time to avert disaster, but there are little time and grave consequences for doing so. A great combination of sci-fi and thriller with solid acting and good pacing. As others have noted, this movie is a fresh concept, and I wondered why we don't see more of the same.

I liked it a lot, except for the last scene which was an attempt from the film maker to throw in a last second plot twist that must have been intended be a guaranteed "home-run" but failed to do so. If anything it ruins the whole narrative of the movie up to then, and could have easily been avoided by just being a tad more linear than going for the "unexpected" alternative. The last scene really serves to make the movie "shoot itself in both feet" and brings everything down. Which is sad, as that scene isn't even necessary to the film or sequence of events. Also I found the movie lacked a bit of "depth", its too superficial. Great potential but ultimately a flop of sorts, I don't recommend it, there are plenty other more awesome movies out there.

This a very late review. I saw the movie back in 2011 and 2 other times since now in 2017.Generally is a good sci-fi thriller that for me is ruined by its preposterous ending.Mind though that the cinematic ending isn't the original. Hollywood producers insisted for a happy ending so they ruined the movie putting a ridiculous twist that simply doesn't make any sense.So, go and see it. Its production is good and there is the proper amount of suspense to make it interesting. I like Michelle Monaghan's performance in this, and Jeffrey Wright's up to a point, but Jake Gyllenhaal is looking to nervous in the lead.
