You want recommendations? Don’t just watch old films. Watch in films that feel like they were made 40 years ago, courtesy of their pacing and depth.
P.S. If you really want to understand me, also watch “Achuvinte Amma” (2005) — not vintage, but Urvashi’s performance there is the bridge between old and new. And yes, I’ll make you puttum kadalayum. Classics require the right snacks.
