Screenplay, Direction and Jake Gyllenhal are top notch. Keeps your eyes glued to screen.

This is the God knows what take on the Groundhog Day idea. Go back to the same situation, try and fix it. Not only is the idea unoriginal, but this time around it is utterly nonsensical, insulting your intelligence. And on top of that, it's boring. That's three major strikes. Just avoid this crap. By the way, Jake Gyllenhaal is one of the most boring actors in the universe. He should never be allowed to play a leading role in a film.

One of the good movie based on the Looping concept. Watched it with a huge expectation after reading some spoilers hence was not a big surprise to me except a few tid bits.

Despite its short run time, Source Code manages to cover a great deal of exciting scenes and twists (some more predictable than others, but they are exciting and warranted nonetheless). Its best to go in knowing a minimal amount of what is going to happen. In fact, the movie itself is minimal, but by answering things that are usually important to the story at a rapid pace, the minimalist effect works well. Some may complain of the ending, but it works within the story well and leaves the audience with a large amount of space to think. All in all, an enjoyable ride that will leave you contemplating what you saw and satisfied with its workmanlike nature.
