Well, 'The Idol' is purely fictional. It was written and developed by the creative minds in the entertainment industry to offer an engaging and imaginative storyline rather than being rooted in reality.
I think it has the potential to be good. A true - story - based idol - related show could offer insights into the idol industry. It could show the journey of an idol, from their humble beginnings to their rise to stardom, and all the hardships they face along the way. This can be both interesting and inspiring for the audience.
Authenticity. Since they are based on real events, they have an air of authenticity that fictional idols may lack. Their stories are real and can be verified, which gives them more credibility.
