Showtime Docu:

We have no right to judge them. They are alive, while Prince is dead.

Christgau is not a fan:

"Appetite for Destruction [Geffen, 1987]
It's a mug's game to deny the technical facility claimed by one-upping crits and young victims of testosterone poisoning--not only does Axl cruise where other "hard rock" singers strive, but he has a knack for believability, which in this genre is the most technical matter of all. When he melds scream and croon on the big-beat ballad, you understand why some confused young thing in an uplift bra is sure it's love sweet love. But Axl is a sucker for dark romantic abstractions--he doesn't love Night Train, he loves alcoholism. And once that sweet child o' his proves her devotion by sucking his cock for the portacam, the evil slut is ready for "See me hit you you fall down." B-"

Showtime has been doing lots of great docs lately MJ & Lenny Kravitz.
