The film is not okay. Nth much interesting happens about the time travel. The problem faced by the protagonist is solved too easily so the plot/suspense can’t sustain for long. The focus of the plot switches for a few times. Some sub plots just appear and disappear out of nowhere. The daughter-n-mother line is not very touching.The hinted romantic element doesn’t exist in the film.
The fact that the female protagonist gets to keep a journal with her while traveling to the past while everything else in the world goes backward doesn’t make sense. Even the guy is supposed to live chronologically, he always suggests he has seen the girl somewhere.
