Here is one of the most critically acclaimed and culturally impactful Hindi movie from the 1980s (1980–1989) which is still considered all-time classics in Indian cinema:
1. **Ardh Satya (1983)** – Dir. Govind Nihalani
A brutal, realistic police drama about an honest cop (Om Puri) crushed by the system. One of the finest performances in Hindi cinema and a landmark in parallel cinema.
