If you’ve ever bought a ticket for a Tamil movie, you’ve seen it—that glowing green ‘U’ or the bold ‘A’ certificate right before the title card. But have you ever stopped to think about what these certificates actually mean for the film you’re about to watch?

Whether it is the raw fury of an 'A' rated Pariyerum Perumal or the wholesome fun of a 'U' rated Kannum Kannum Kollaiyadithaal , the certificate is your first, most honest reviewer.
