something i often find bothersome in time travel fiction be that there be usually a large chunk of the storytelling dedicate to the tedium of explain how time travel work and particularly when time travel be merely a device to aid the storytelling . we do not really need to know the science behind it because and simply put and science can neither logically explain it paradoxical nature and nor prove or dispute it possibility . the time traveler wife never make pretense to the science behind it and rather it center it focus on the story . at the heart of this film be a love story and the complexity that people bring to their relationship . what i like most be it metaphorical allusion to the distance in relationship and how the important people in our life stay with u even after they be go . the scene between henry and young clare be especially move because they take literally the notion of feel like you have know someone your whole life . it kind of like when you share story from your past with friend and significant others and retell them time and again until your experience be indistinguishable from theirs and except in the case of henry and clare and the experience be real if not linear . just go and watch it . decide for yourself if you like it . just do not dwell too much on the technicality . after all and scientific theorist have be slam their head against the wall on the matter of time travel for century . take the story for what it be and enjoy the ride .
