So is the general consensus in the jazz community that he is a phony? He seems genuine enough in the interview that I linked to.
The "jazz community" is much larger and more diverse than just those who post here. There are many, including myself, who enjoyed the series - who were greatly appreciative of the many clips provided, and also got a lot out of the talking head interviews (including Wynton's - turns out he's a much better teacher than composer or bandleader).
Ultimately, the series is a good resource. Most posters here are simply encouraging you to watch the series and form your own opinion.
