I agree with assassinator.
There is a big dearth of proper crime writers for both hte big screen and small screen. One needs to pay a good writer and respect the copyright issues by the production houses. This does not happen to a large extent in India.
No I am not getting negative. There are many shows in the west shown on PBS or local channels that are good well written crime shows. Many can't be shown here as they are in water tight copyright material.
In India, crime writing as a genre requires a lot of prerequisites. Many writers don't match up to these criterion. So the result is what we are seeing on all the so called popular crime shows.😊
