I'm not convinced that Fletcher’s little smile at Andrew in the ending scene is satisfaction that Andrew has proven himself and has finally “made it”. I think Fletcher is pleased with himself that he has finally achieved his own personal, life’s goal of creating the next Charlie Parker.
Thanks, Mike. Wow, I never saw it that way, but it makes sense. Fletcher is not really happy for Andrew, he's only happy for himself. Maybe that's why they only showed his cheeks rise up and not the full smile with his mouth. Andrew was just a pawn/tool supporting Fletcher's life long goal.
