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 behindhand 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 behindhand it, rather it centers its focus on the story.
