I've seen those criticisms but you have to remember this is before the Internet and before cross communication with other countries, etc. It's a stretch, do those critics expect them to be investigating something and spending hard earned money visiting all countries around the world to verify some random fact of an artist? The documentary is based on the personal experience of some fans in South Africa and people that give that criticism don't seem to understand the context. Plus, the film (as its title is named) is about THEIR search for sugar man not about the life of the guy itself or all the facts around his life.
