After going through this whole thread, it feels like this discussion is moving towards defending what we love/believe with what we have rather than receiving/accepting constructive criticism, which should always be appreciated.
Everything that an industry produces can not please everyone. Every content making industry needs to hang onto commercial contents for benefits. The films that travels the other path, you all know what happens to them on financial side. It's not theatre where Art is above all, it is business and has to be dealt that way.
I have been watching movies on Goldmines or similar providers for many many years, when they were pretty amature and we could hear original sound tracks in between. Yes I know I am quite old by now
. The viewership of these commercial movies are always higher, so they are predominantly dubbing these contents only.
And good movies are there in every industry along with the mass ones.
Tamil industry produced movies like 'I' , 'Aparichit' as well as many mass movies. Similarly we have 'Hemlok Society' in Bengali but have a mass entertainer like 'Paglu'.
In Telugu, I will suggest you Agent Sai Srinivasa Athreya .
