The actual laws of thermodynamics, in case you need a refresher:

• energy cannot be created or destroyed
• the entropy of any isolated system always increases
• the entropy of a system approaches a constant value as the temperature approaches absolute zero

Manel, a neurotic scientist, is out of his depth when he dates his dream girl, Elena, a beautiful model. So he seeks comfort in his precious laws of thermodynamics to reassure himself that love is just another quantifiable thing, an equation he can puzzle out and make sense of. But the more that real life seeps in, the harder he has to spin things to keep the laws working for him.

Using the rules of thermodynamics as a construct for “solving” love is interesting, at least at first. Eventually it involves more shoe-horning than any script worth its salt really should, and the effort becomes tiresome.

Vito Sanz and Berta Vazquez are perfectly charming and thanks to them, I can kind of see how a playing, witty movie like this might have worked. But whatever lightning bot of creativity struck at the outset, it faded quite quickly and it fails even at sustaining what it started with. I was unconvinced and unimpressed by this film unfortunately – maybe it works in theory, but the proof is kind of painful to watch.
