It depends. Sometimes web series claim to be based on real events but take creative liberties. You'd have to look into the production details to be sure.
Accuracy is a key characteristic. It should stay true to the facts as much as possible. For example, in a series about a historical event, the dates, locations, and main events should be correct. Another characteristic is good character development. Since it's based on real people, the series should be able to make the characters come alive, like in 'The Crown' where the characters of the British royal family are well - developed. Also, it should have a good narrative flow. It can't just be a list of facts but should tell a story in an engaging way, like how 'Making a Murderer' unfolds the story of a man wrongly convicted in a suspenseful manner.
One great example is 'The People v. O.J. Simpson: American Crime Story'. It tells the real - life story of the O.J. Simpson trial, which was a highly public and controversial case in the United States. The series does an excellent job of portraying the various characters involved, from the lawyers to the witnesses. Another is 'Mindhunter'. It is based on the true - life experiences of FBI agents who interview serial killers to understand their mindsets and develop criminal profiling techniques. It gives viewers a fascinating look into the early days of criminal psychology research within the FBI.
It's possible that the 'Kaafir' web series has some basis in real - story. It might incorporate real - life situations, emotions, or conflicts. For example, it could be inspired by stories of people who have had to fight against false accusations or deal with cross - cultural misunderstandings. However, it's also likely that the creators have added a lot of fictional elements to make the story more engaging.
The Crown is also excellent. It's based on the true story of Queen Elizabeth II's reign. It delves into the personal and political aspects of her life, from her early days as a princess to her long and eventful time on the throne. With high - quality production values, it portrays the British monarchy, its traditions, and the historical events that shaped the nation during her rule.
