Well, i'd most like to see Marketa Lazarova + Mandala. 

Of the 16 i've seen, Subarnarekha is the best; marvellous use of space + nature by Ghatak, the inventive left-wing Bengali director. It has some late nocturnal expressionist scenes that may bring to mind Cloud-Capped Star. I do find Bijon Bhattacharya, who played the father in the latter and the paternal friend in Subarnarekha, irritating; i suppose Ghatak picked him for parts, as his playwright friend from their challenging theatre days. Ghatak could be uneven, but made interesting use of lighting + sound. El is probably underrated Bunuel, a tale of male obsession + jealousy. Still, most of the 16 i wouldn't class as gems.

Sight + Sound is still too Anglo-American orientated for my lking.
