Sticking with single genre will help Marathi filmmakers immensely.
What makes Marathi movies unwatchable to me is mixture of all genres. This is true for most indian film industries too. I think it will help a lot to stay with a single genre. With exception of fantasy and action Marathi movies are too plagued by having romance,drama, comedy and at the end some preaching all in 2 hours. There are almost no fantasy or action movies. It's either mainly social commentary or double meaning adult comedy and love story. This is just my observation. If you have any examples that go against this I would love to watch those movies.
