Nunca me abandones

The concept of the story can be well appreciated, as it probes into one of the most vexing conundrums of medical and societal ethics ever attempted in modern times. However, there are various plot holes, which I won't delve into here, as such might provide unintentional spoilers.

Other films, which are perhaps a bit more technically realistic and futuristic, have probed this same conundrum in their own context, and that may be the ultimate shortcoming of this production. Even now, medical science is progressing in directions which could eventually make this depicted scenario completely obsolete.

Having said that, though, the caliber of acting and storytelling here is first rate. The focal point of this production is not on a sci-fi style of motif, but rather exploring the social complexities that this type of depicted scenario might create, and likely would create if something like this were ever to come to pass.

As a character study of the human condition under extraordinary circumstances, this is a compelling enough production to hold almost anyone's attention. Everyone delivered their characters exceptionally well, but Carey Mulligan really shines here.

As other reviewers have suggested, this may not be for everyone. No action scenes here, no glitzy sci-fi tech and all that, but as a compelling story remarkably well told and acted, the time spent watching this is not wasted.
