17 years after his death, the world's most iconic pop star has once again got people talking. The biopic, Michael, which chronicles the life of the legendary singer's rise to fame –from his involvement in the Jackson 5 in the 1960s to the 1980s Bad tour– has just been released. On paper, it had the potential to be one of the most compelling biopics ever made. Not only was Jackson the biggest pop star on the planet (his Thriller album remains the best-selling album of all time), but his life was also profoundly marred by controversy.
