I prefer this one over the 2016 film which in my opinion was too shallow, confusing, and directed in a strange way which omitted too many important details, while giving often biased views of her life.
This 2-part TV film however also omits a large part of Dalida's life (the first 22 years of her life in Cairo, Egypt) where she was born and participated in several activities including her 1955 Miss Egypt Beauty Pageant which led her to participate in several Egyptian movies, until finally a French director discovered her while filming The Mask of Tutankamoun in Luxor, and persuaded her to try her luck singing in France.
Seems like both directors of this movie and the 2016 one don't want to show any details about her 22 years of living in Egypt. What a shame since she was already well-known in Egypt before moving to France and becoming an international star there. I'm sure a lot of fans would have liked to see what life in Egypt was like back in the 1950's-quite a modern, cosmopolitan, prosperous place to be full of people from different parts of the world including other Italians like Dalida's family, Greeks, Armenians, British, and even French.
