I HAD to watch the movie, as soon as I had realized that it involved Time travel. Well, not Time Travel in true sense, but maybe even more exciting!
I loved how the film was shot, directed and edited. The sense of originality was in almost every time the actor went back into those 8 minutes. Even after we were witnessing the same incidents again and again, not once it felt repetitive, since every time the execution was different!
This film had its moment of awe, jaw dropping moments and spine chilling visuals, like the explosion, when least expected. And that moment when time stopped to reveal the passengers in the perfect mood, the actor wanted them to be. At this point, I would quote a review from IMDb, that is possibly the best explanation:
And what happens in the last iteration is what should have made the movie memorable. Knowing this is his last remnant of consciousness, what he does the last time is make everyone in the train car happy. He's learned a great deal about them the other times through. He bets a comedian (whom he has recognized from television) all the money he has that he can't make everyone on the car laugh. The man takes the bet and proceeds to do just that. As the seconds tick down to the inevitable end, when they'll all be incinerated, he takes the girl in his arms, tells her he loves her, and wants to be with her forever. The frame freezes and pans the whole length of the car, revealing every passenger laughing or in various states of bliss. This is the instant that will see the hero into eternity.
