As other reviewers have noted, this film is more about relationships than it is about time travel. With love as the central theme of the film, it's strangely and pervasively bloodless. We're instructed by music cues how we should feel about these characters, but they never generate their own spark. These people make a lot of money doing who-knows-what, with endless opportunities to spend disposable income. They live in spare, minimalist surroundings and speak entirely in cliché. They care or don't care about each other on cue, to serve the narrative.
The aspects of time travel were interesting, but not reasonable. If any trip into the past allows for time ripples to obviously and thoroughly alter and destroy other people's lives, it's hard to believe time travel services would operate freely and publicly, with just a signature on paper binding them not to mess things up.
