What's the Story?
THE LAWS OF THERMODYNAMICS tells the story of Manel (Vito Sanz), an astrophysicist who tries to cram his personal interactions and relationships into carefully boxed, fully understandable scientific principles. Although he doesn't see it in himself, fully engaging with the world around him as it really is would be way too scary -- until he meets and falls for the beautiful Elena (Berta Vazquez). Elena knows that people can't be defined or hemmed in by the laws of physics, or any other scientific principles. They're unpredictable, but most importantly they need to feel free to make their own choices about their lives. Can two such opposites be happy together?
Is It Any Good?
This movie has a lot going for it on paper: a meet-cute, an opposites-attract couple, a quirky gimmick that applies laws of physics to human relationships, and an attractive, talented cast. Unfortunately, the gimmick in The Laws of Thermodynamics of cutting back and forth between "talking head" experts who explain the science and the story of Manel and Elena's romance pretty quickly bogs down and starts to feel overused. Add to that a script that plays mostly as mildly funny and offers few real laughs, and the movie stays pretty firmly in "OK, not great" territory.
Teen interest is most likely in the sex and nudity. Those and the profanity make it best for oldest teens mature enough to handle the adult situations and sexuality.
Talk to Your Kids About ...
Families can talk about the sex in The Laws of Thermodynamics. Is it gratuitous? Why include it? How much is OK in movies, books, games, etc.?
What about all the profanity? Is it realistic? How much is OK for kids and teens to hear in movies?
Did you learn anything about thermodynamics, or physics in general? Why do you think the movie goes back and forth between the science experts and the story?
