Since I was a kid, I’ve been crazy about time traveling movies, just any scifi geek. If you think this movie has anything to do with Back to the Future, forget it. The Time Traveler’s Wife is a love story in which the two main characters have different timelines (and the viewer has a third one).
Time-travelling wise, the movie is very inconsistent and not appealing (although they got the being naked part right), but it works as a love story where there is an opposing force in between. I haven’t seen it, but I would say it should feel like The Curious Case of Benjamin Button. And it’s not an “and they lived happily ever after” story (well, it depends on which timeline you are in….), which takes it to a different level.
