In this poignant documentary, director Vinnoth Krishnan turns the camera on his own family, capturing the quiet, profound passage of time within a single household. The film intimately follows Krishnan Govindan and Mani, an elderly couple navigating the rhythms of daily life in their ancestral home. Their routines, from tending a small garden to sharing meals, are lovingly observed, revealing a deep, unspoken bond forged over decades. The central conflict emerges not from dramatic events, but from the subtle, inevitable shifts brought on by aging and the looming presence of memory. Letchumy, a family member, adds another layer to this delicate ecosystem, her presence highlighting the generational currents flowing through the home. With a meditative and tender tone, "Time Keeps Marching On" offers a deeply human and universal meditation on love, loss, and the beauty found in life’s quietest moments, asking viewers to consider what truly remains as the years slip by.
