Donot watch documentary films if you personally dont want to witness the backstage life of these extremely hardworking and dedicated performers who practice nonstop and always give their 200% on stage no matter what.

Coz documentary films aren't concert films or VCRs, they always include raw emotions of the performers in situations both good and bad, their life beyond the stage and their reality, the fact that they may be gods on stage, but they are afterall only humans behind it.
