Something I often find bothersome in 'time travel fiction' is that there is usually a large chunk of the storytelling dedicated to the tedium of explaining 'how' time travel works, particularly when time travel is merely a device to aid the storytelling. We don't really need to know the science behind it because, simply put, science can neither logically explain its paradoxical nature, nor prove or dispute its possibility. "The Time Traveler's Wife" never makes pretenses to the science behind it, rather it centers its focus on the story.
At the heart of this film is a love story and the complexities that people bring to their relationships. What I liked most was its metaphorical allusion to the distance in relationships and how the important people in our lives stay with us even after they are gone. The scenes between Henry and young Clare were especially moving because they took literally the notion of feeling like you have known someone your whole life. It's kind of like when you share stories from your past with friends and significant others, retelling them time and again until your experiences are indistinguishable from theirs, except in the case of Henry and Clare, the experiences are real if not linear.
Just go and watch it. Decide for yourself if you like it. Just don't dwell too much on the technicalities. After all, Scientific Theorists have been slamming their heads against the wall on the matter of time travel for centuries. Take the story for what it is and enjoy the ride.
