Heartiley Battery series plot:

Sophie is a science enthusiast who invents a machine that determines the exact percentage of love someone has for the other. Evidently, the machine becomes the cause for some couples to break up. Sophie stumbles upon Sid, a comic artist, who believes love is more than what machine reads and challenges that Sophie will fall for him soon. Will she fall in love, and if so, will they unite?

Heartiley Battery series review:

Heartiley Battery begins with what is supposed to look like a meet-cute scenario. Sid who is running away from a bunch of men, ends up near Sophie and lies to the goons that they are a couple. An unconvinced Sophie plays along, and here’s where the two strangers turning into something more is touted to begin. But Heartiley Battery, with all its efforts, is both a conveniently written series and a low-offering watch.

At the crux of Heartiley Battery is the story of a woman who sees love as nothing as logic, and a man for whom it is just magic. Sophie has lost the belief in love, thanks to her parents’ separation during her childhood. Meanwhile, Sid is someone who has strong feelings about love, and that is all we know about him apart from being a comic artist. We are presented with a parallel story, an animated one that of star-crossed lovers who are heirs of opposing kingdoms. It is the comic that Sid is working on, and simultaneous narration just feels too hard to draw any parallels. With the main conflict of the series being two individuals of different faiths in love, coming together, giving a possibility of whether they would fall in love, the series takes a long route to explore it. But it takes forever to understand Sophie and Sid, sometimes until the last episode, leaving you to question what makes them fall for each other. Had the series worked on a little more to show who they are, Heartiley Battery could have had chances to become more engrossing.

The show, with six episodes in total, with an average of 20-25 minutes duration, is crisp with its runtime but each of them barely gives enough to move on to the next. A historical start to each episode, a device that can measure love, and two contrast-minded individuals, the series tries to dabble a little more than just a romantic drama, but with each of these threads not fulfilled to the maximum, Heartiley Battery becomes a watch that tries to be just average.

Heartiley Battery series verdict:

Heartiley Battery comes with its flaws and might not be a fulfilling watch for those who are used to a plethora of romantic films and K-dramas. Had the series delved a little more into understanding its main characters and explored the conflict, the science-fiction aspect and dug deeper into its episodic nature, Heartiley Battery would have emerged as a decent watch.

Heartiley Battery is streaming on Zee5 via OTTplay Premium
