Yes, points which Usha Madam and Kalyani Madam discussed is exactly rights. Being from Kerala, I can easily say that Malayalam films are much more superior to Bollywood and many other colossal film industries in India, in terms of story ideas, concepts and its treatment. Even if I have not seen many Bengali and Marathi Movies, I have heard a lot that they maintain certain standards as in Malayalam Industry. Actually this is a major topic to discuss about. With the experience of watching many Malayalam movies, I can say that a lot very good movies are made in very low budgets in Malayalam. One of the main reasons I find is that, Malayalam movies don't go to much behind stars and their stardom. Of course, there are exceptions. And the topic of this thread, even in Malayalam movies, we can easily find some influences of foreign movies. But, those movies are remade in a good manner mixing up the Kerala culture into it.
