So many helpful suggestions here, and i've been scouring imdb ratings too. Over 18,000 films listed there, so it's quite ridiculous what a miniscule percentage i've seen. I'm ordering the book 100 Bollywood films to help me catch up on the subject.

I'd be interested in any opinions here on the following, which i'd like to see:

Devdas (Barua)
Rang de Basanti (Mehra)
The Bogeyman (Aravindan)
Nayakan (Rathnam)
Chandralekha (Vasan)
Tarang (Shahani)
Ajantrik (Ghatak)
Pushpak (Singeetham)
The Forest (Karnad)
The Seedling (Benegal)
Taxi Driver (Anand)
Black Friday (H.Mukherjee)
Siddheshwari (Kaul)
Sangam (Kapoor)
Piravi (Karun)
Anand (Mukherjee)
The Jewel of Shiva (Vishwanath)
A Folk Tale (Mehta)
