As far as creativity is concerned not a single channel has shown creative content in every show. There were some shows which were typical which we don't like to watch. When the audience watch the show it is because of their favourite actor or they have liked the promo. Showing a romantic genre with the male and female lead having great chemistry is not different. Different is also offering a new genre.
I know Star plus is trp hungry and it shuts the show if it doesn't do well. Shows like Dahleez, POW, Everest were creative in real terms. But this shows are less liked as they don't run on prime time. I don't like shows like ishqbaaz, yeh rishta, yhm. So typical but still they run
Sony has been following Star plus and doing mythology shows. But Star Plus Mahabharat was the best. Sony came with Pehredaar Piya ki which I will never choose to watch. Yeh un dino ki is good but again a same genre. Same goes with kuchh rang.
I cannot say anything about Colors as it has the least creative content.showing naagins is ridiculous. Same goes with Zee tv as I have not watched a single show on it.
