Taylor's Examined Life was fine. And I'm admittedly smitten by Zizek. Still, my main reason for bothering to rent this was the soundtrack by A Hawk and a Hacksaw. (I will stand by any band so taken by Parajanov's Shadows of Forgotten Ancestors that they were compelled to write it an alternate soundtrack!) The film itself is exactly as you might imagine - an enjoyable, if flimsy, document of a bit of time with Zizek.
It's not much of a documentary, but it's a good glimps of what an extraordinarily childish, crazy, geniusly interesting person Žižek is. If only all people would be as "human" and true as he is. If you expect a lot of the philosophical insight, forget about it (read (his) books!) - it just shows the most known ideas of his.
