If you went into seeing Maari with anticipation based on the preview, prepare to be let down. The most entertaining parts of the film are already showcased in the trailer, and the actual movie lacks the vibrant energy seen beforehand. Ultimately, Maari feels like a prolonged buildup that doesn’t deliver. The story unfolds within a slum setting, where Maari (played by Dhanush, who brings vitality to the character) is a small-time criminal with a passion for pigeon racing. His rival is Bird Ravi (Mime Gopi), consistently overshadowed by Maari's rising status as the preferred associate of a larger crime boss, Velu Annan (Shanmugarajan). A new police inspector, Arjun Kumar (Vijay Yesudas, in his debut role), enters the picture, determined to solve an old murder that is the source of Maari’s fearsome reputation. There's also a subplot involving red sanders smuggling, seemingly intended to give the narrative some relevance. Perhaps after Vaaya Moodi Pesavum, which was largely silent, director Balaji Mohan aimed for something relatively straightforward and selected this script, which contains its share of familiar tropes. The director seems conscious of this and attempts to maintain a light tone, preventing scenes from becoming overly dramatic (a task greatly aided by Robo Shankar’s excellent performance as Maari’s comedic sidekick, Sanikizhamai), but this approach doesn't suit the film, which is essentially a celebratory action movie. Story developments are handled with too little seriousness—even the hero’s imprisonment—leaving the audience feeling disconnected from what's happening. Worse still, after employing various techniques – a stylish beard, fashionable clothing, trendy shirts for delivering dialogue (Senjuduven), and an air of nonchalance – to establish his hero, the director fails to provide him with formidable opponents. A protagonist is only as compelling as their antagonist, and the villains here are hardly threatening. Both Vijay Yesudas (portraying a character reminiscent of Virgil Sollozzo in The Godfather) and Mime Gopi are underdeveloped and lack impact; they never come across as a genuine challenge to the hero. However, Maari isn't quite as disappointing as Anjaan (another recent film featuring a star playing a gangster that failed to live up to expectations), although it does get close at times. There are some unusual touches suggesting potential, though they aren’t sufficient for the movie to truly ignite. The strongest scene—Maari reasserting his dominance—is a classic masala moment and a clever nod to the scene in Baasha where all the underworld figures pay homage to Rajinikanth. In this sequence, the villain's henchmen arrive at the market to collect payments from the shopkeepers, and Maari, unfazed, calmly sits with his feet on a table while setting off fireworks, unsettling them. Then, recognizing who’s in charge, people begin placing their money on Maari's table. It is a quietly powerful scene, and what the film desperately needed were more like it. Instead, we are given scenes that suggest something significant but ultimately fall flat. Consider the instance where Bird Ravi is left to nurse his wounds after Maari refuses to pay him; one expects him to devise a plan for revenge, but he simply complains to Arjun instead. Even the romance isn’t carelessly handled, though it adheres to the familiar Tamil cinema formula of an educated and attractive woman falling for a rough-around-the-edges but kindhearted criminal. As viewers might anticipate when Sridevi (Kajal) begins to pursue Maari after he assists her with a financial problem, Balaji Mohan introduces a surprising twist. If this level of creativity had been present throughout the film, we would have received the quirky mass action movie that was promised in the trailer.
