Here is a very interesting and creative piece, noso much a romantic drama as a sci-fi peice on time travel. The story concentrates on the leading male who travels through time, travels to places and times without warning, he doesn't know where he's going, when he's going, or when he'll be back. The story also brings us his spouse, the woman who also must suffer constantly waiting for her husband to return.
It sounds like a good recipe for tears, heartache and heartbreak but really its not all that touching. Although you feel sorry for the wife you feel slightly more sad for the time traveller, the man who'll be pulled away randomly to a time and destination unknown.
Overall: It's a good movie, at times it can be little bit confusing which is another reason why it doesn't work as a tear-jerker. You care for the characters but there's not enough to make you want to hug your loved ones.
Still i recommend watching, very entertaining.
