Corrected entry: When they send the warning note to Denzel Washington from the present to the past, it takes so much power that the whole "time machine" system as well as the power in the whole city breaks down. When they send Denzel back to the past it happens much faster and without any problems. When the "transfer" from Denzel to the past works that fine, a transfer from a simple paper with some words on it should be no problem at all. They also said that they tried to send a hamster to the past and that it did not survive it. Why should an adult survive this?
Corrected entry: What caused the original time-line to change was essentially the terrorist jumping on the ferry instead of riding his motorcycle to the bridge to view the bombing. Nothing unusual was done to cause the terrorist to jump to the ferry as opposed to the original time-line where Denzel was present and doing everything the same up to that point, since both time-lines had Denzel using the car the terrorist would be familiar with. This of course operating under the assumption that Denzel saved the girl from getting her fingers cut off in both time-lines, which would only make sense plot-line wise to avoid plot-holes. Her fingers probably were dismembered in failure to save the ferry in the original time-line, but then it would be impossible for her body to end up upstream 2 hours before the explosion. Mistake is the car triggered the terrorist to jump to the ferry in the new time-line but not in the original time-line.
Corrected entry: In the first time line Clair lost 4 of her fingers and she washes up on shore at 10:48. In the second time line Doug saves her from loosing her fingers and stops her from dying by the bad guy burning her and dumping her body. Back to the first time line and finally to the plot hole. If she loses her fingers in the first time line and is suppose to be dead, then how is she in her apartment to answer the phone when Beth calls? In the second timeline Doug tells her what Beth says to prove he knows what is going to happen in the future, he knows this because he played her messages back in the first time line. How did she answer the phone if she was dead and about to wash on shore?
Corrected entry: The bad guy soaks the woman with fuel. The bad guy then shoots Denzel, and runs outside. He then fires at a propane tank that causes the entire building to explode. The fireball is enormous, and flaming debris is everywhere, including being inches from the woman. But she never ignites.
Corrected entry: In the original timeline in which the movie begins, Carlin is investigating Claire Kuchever's death including her missing fingers. In this same timeline we hear his co-worker tell him that his [Carlin's] fingerprints were all over Kuchever's home. We later find out that the killer cut her fingers off. However, the reason Carlin's prints are all over the home and the reason that certain items are set up in a certain way, was because Carlin was in the home with Kuchever after preventing her death and preventing her fingers from being cut off.So the flaw is: if he kept her fingers from being cut off, he would have been in the home and would have left the prints but her corpse wouldn't be missing fingers [if she died at all]. If he didn't prevent her death and dismemberment, he wouldn't have left his prints and certain items in her home. These scenarios could not both occur however.
Corrected entry: After the ferry explodes at the start of the movie and they start evacuating survivors, there is a shot of people waiting on the dockside talking to a cop. One of the people, a black man with dreadlocks in a white T shirt is smiling at the cop, while the others are shouting a him. Bizarre considering the disaster that had just occurred.
Corrected entry: After going back in time, Carlin appears at Charity Hospital. Charity Hospital has been condemned since Hurricane Katrina and would have still been flooded inside during the time frame of the movie.
Corrected entry: Carlin realizes that the bomber only needed to steal Claire's vehicle because Carlin's partner shot up the windshield of and got blood in the bomber's own car. Otherwise Claire would not have become involved at all. The problem? As they are watching the events of the past, they see the bomber calling Claire about her truck BEFORE Carlin's partner confronts him and shoots his windshield.
Corrected entry: Carlin was wounded when he saved Claire from being killed and her fingers dismembered. After that Claire bound Carlin's wounds in her home and put bloody bandages into a basket. It is not possible to have dead fingerless Carla and the bandages in the same time branch.
Corrected entry: During the film, when Doug Carlin is in the "present" unaltered time, he sees things that eventually happen later in the movie when he goes back in time. What doesn't make sense is that if he saw all the other things, and considering he saved the ferry, how could he see the ferry explode at all in the beginning?
Corrected entry: Surely if Doug can go back 4 days and he's saved the people on the ferry then why can't he go back again to stop Larry dying?
Corrected entry: At the beginning of the movie, one guy in Doug's office gives him Claire's message, written on the outside (colored side) of a candy wrapper. When Doug goes back in time, the guy gets Claire's call again and he grabs the candy wrapper, beginning to write on the opposite side of the wrapper.
Corrected entry: Just before the bomb explodes at the beginning of the movie, the guard is looking for the car playing 'don't worry baby' on it's stereo. In the final timeline the disaster has been averted, the bomb having gone off, and the ferry docked. After this, when Carlin is in the car, the same song is playing, but the bomb was set to a timer.
Corrected entry: Using logic then this movie does not make sense. The "you can save her" on the fridge, the blood stained clothes and the cotton swabs. These were all done by Doug in the past. If Doug in the past managed to show this to future Doug as he was looking around the house for clues then surely he'd already done the deed of stopping the ferry.
Corrected entry: While listening to Claire on her cell phone, why can they hear the other side of the conversation?
Corrected entry: Carlin forces the other agents to confess about the fact that they were really looking at the past in real-time and not looking at 4 day old footage. The way he does this is to shine a laser pointer into the equipment. It took amazing amounts of effort and machinery to send any item back in time. Even accepting that the infinitesimal size of the laser beam's particles would make it very easy to send the beam: WHY would it work that way pointing it at a MONITOR? It's just a viewing screen and is only 1-way. Further proof that it's just a monitor and not a 2-way portal: When they zoom through the scenery with the cameras in space (and yes, they were honest about the placement of the cameras) the screen shows that it takes a bit of time to render/display the image.
