Prem, a 12-year-old boy, dreams about maths since he likes it so much. While Prem's mother Priya (Punam Patel) is proud of his aptitude for square roots and equations, Prem gets bullied at school for being a nerd. As Prem tries out new things, even his closest friend Jerome (Max Malas) isolates himself from him. So when Prem learns that Suresh, his late father, was a legendary emcee and rapper, the little kid embarks on a quest to find his own voice.

'World's Best' is a coming-of-age story about a nerdy South Asian child with a lot of expected beats, but they play out in unique ways. Additionally, it helps a lot that Prem is played by newcomer Manny Magnus, who is incredibly skilled and expertly transitions between the geeky math guy and a captivating bar-spitting rapper with fluid motions. You are drawn into the father-son interaction between him and Utkarsh Ambudkar by their strong chemistry. The carefree atmosphere of Ambudkar fits the upbeat persona that Suresh is meant to have well. Punam Patel excels in her role as Priya, Prem's adoring mother, who is adjusting to life as a single parent following the death of her husband. Priya is battling her own bereavement and isn't yet ready for Prem's efforts to explore his father's past. Despite the little space available, this approach presents a rather compelling dilemma over their connection.

The movie excels in several areas, including its appealing hip-hop, which features both original songs written by Utkarsh Ambudkar and classics from the genre. It's entertaining to watch Ambudkar and the young Magnus perform together. Suresh and Prem approach their rhymes in a distinctive way that perfectly ties in with the latter's nerdiness. Each of these enchanting tunes has a bright, foot-tapping energy that is uplifting, and the production values are exceptional. The underlying concepts of the movie are intriguing, but they aren't fully explored. Nevertheless, "World's Best" is a heartwarming and deliciously amusing family movie with a breakout performance from Manny Magnus.
