If there is a criticism to be lobbed at Nelson's judicious but otherwise highly entertaining tribute, it's that it too often plays the role of the fawning, autograph-hungry fanboy, willing to accept all of the abuse Ellison wishes to hurl at it.

It would seem no easy task conveying the essence of a bigger-than-life figure like Ellison in a 96-minute film. But Nelson, producer of Werner Herzog's Grizzly Man, makes it look easy.

All told, Ellison is a fascinating person to spend 96 minutes with. But you probably shouldn't risk that 97th.

Ellison arrogante, mal-humorado, impulsivo, auto-indulgente, prolixo e agressivo. ... tambm brilhante, articulado e divertidssimo %u2013 exatamente como este belo documentrio que gira em torno no de sua obra, mas de sua personalidade.
