Well with me it's much worse, as I only started watching films regularly in the 90s. So from there on i know quite a bit, but the further I go back, the fewer I've seen. 
That's probably also the main reason why I am mostly watching "older" films all of the time 

Seems like the situation in India is a bit similar to the situation here in germany. Here also everybody thinks german cinema died with Rainer Werner Fassbinder, and from the 70s, most people only now Herzog and Wenders works (and maybe some Straub/Huillet and Schlndorff). When you also had here, back then even internationally known directors like Herbert Achterbusch, Hark Bohm, Bernhard Sinkel, Helmuth Costard, Hans Geissendrfer, Alexander Kluge, Reinhard Hauff, Peter lilienthal, Alexander Kluge, Edgar Reitz, Hans-Jrgen Syberberg or Werner Schroeter to name but a few. And this is only West Germany! The east had their own great directors 
Speaking of the current times, this quantity and quality is imo matched, but this time there are no outstanding figures and no movement to hang the attention on (as well as not many international awards.) It is interesting to note that the "Ne German film" movement when it began in the early 60s wasn't appreciated here in Germany. It was only after they had been internationally recognized, that german critics took up their case in the 70s. 

Would be great to see you take some unknown Indian films under closer observation! 

I'll try to do something like that with german and Yugoslavian (slovenian) film over time (cause i have naturally access to much of it), but I'm often a lazy bastard.
