Tony Scott had previously directed good thrillers with little action. However, he has a distinct style of narrating a story that captures our attention to the point where you would miss or desire adrenaline pumping action sequences. After seeing his other films starring my favourite actor Denzel Washington, "Man on Fire," "Unstoppable," and "Pelham 123," I'm not sure whether to classify this one as a science fiction thriller or a crime thriller due to a time-travel plot. This flaw is, of course, overcome by a very good ensemble of good actors.

The film is watchable because of the photography, editing, background score, and skilled directing. It is unfortunate that this talented filmmaker died tragically in his personal life. It is paradoxical a good number of artists giving thought provoking stories on reel life fail in real life.

When Denzel's character first went to Laura's house, one of his coworkers informed him that he had left finger prints all over the place. Then we find out it's because he WAS there, and not only were his fingerprints but also his blood left behind. In real life, some sort of connection would have been made. However, shotty police work is acceptable.

Why doesn't Denzel's character TRY to change the outcome of the scenario as he travels back in time? Why would he steal an ambulance after seeing one crash at the dude's hideout? Why should he stop cleaning up after seeing blood at Laura's house?
So, if he knows when and where the explosion occurs, why doesn't HE, as a credible ATF agent, inform law enforcement so that the perp can be apprehended immediately before or after he drives on to the boat, due to time constraints? In this case, prevent any passengers from boarding the boat. Worst case scenario, the boat explodes with no one on board.

Apart from these minor gaps in common sense. I was on the edge of my seat the entire time I watched it for the second time. I strongly recommend it.
 The movie has such a good and shocking story that at one point I prayed it wouldn't die... even though I knew it would:(
Denzel Washington is a movie legend; I haven't seen a bad movie from him... and when you hear his name in a movie, you know it's good and worth seeing!
Déjà Vu 10/10.I will highly recommend you guyz to enjoy this movie.HAPPY MOVIE ♥️
