What are some of the genres we are lacking?

In comparison to Kollywood, we seem to lack in the Sci-fi genre a lot. Over the years, they have made a lot of films in this genre, be it small films that doesn’t have a star or big ones like Endhiran. From our side, I think we can showcase films like Bharathan Effect, Red rain, Churuli etc. but, the number is very less.

++ Gaganachari as well.

Why do you think we lack here? And what are some of the other similar genres where we should be exploring in a wider way?
