The phrase resonated with fans and movie enthusiasts, who began using it to describe the evolution of Tamil cinema. It symbolizes the transition from the golden era of Tamil films to the present day, where new trends and tastes have emerged. The Kaalam Maari Pochu movement is not just about nostalgia; it's about appreciating the classics while embracing the changes in the film industry.

The movie revolves around two friends, Muthusamy (Santhosh Narayanan) and Pandian (Shanthanu Bhagyaraj), who have different personalities. Muthusamy is a carefree and simple man, while Pandian is a business-minded person. They get involved in a series of misadventures, which lead to a change in their lives.

It sounds like you're referring to the popular Tamil phrase (காலம் மாறிப்போச்சு) — meaning "Times have changed" — often used in movie dialogues, reviews, or memes, especially in the context of Moviesda (a notorious piracy site).
