I haven't seen an Indian movie before. But I want to start with a good one.

Depends if you want some shitty Bollywood crap or actual cinema... Some movies I suggest, that are different from that song and dance routine
1. Omkara (Indian adaptation of Othello)
2. No Smoking (Kafka inspired movie, and an idea is actual plot of the movie, can be a bit confusing though)
