Interesting that with all the great educational and documentary fare available on Netflix, every one of you guys is recommending escapist entertainment. OK, Orange is the New Black is pretty good. So is Lillyhammer. If you like sci-fi action and aren't offended by gay folk being portrayed as normal people, check out Sense8.
But 90% of what I watch on NF is non-fiction. I became a Rush fan after seeing Beyond the Lighted Stage on Netflix. Runnin' Down a Dream (Tom Petty and the Heartbreakers) is a must-see. Ditto for other biographies Chasing Sound (Les Paul), The Language of Music (Tom Dowd), and Atlantic Records (Ahmet Artegun). Then there are the making-of docs such as Classic Albums: Making Of Dark Side of the Moon.
And don't forget the concerts. Pulse (David Gilmour), Hell Freezes Over (Eagles) and Premonition (John Fogerty) are three that offer outstanding performances and great audio quality.
