Your suggestions about the film are quite accurate, arsaib. The first thing that came to my mind when I thought about writing a review (which I did - in german, of course) was: As If Werner Herzog, Andrzej Zulawski and Friedkin himself collaborated. The ironic, in the finale even extremely sardonic sneering note by Herzog (unbelievable - this film really is a swan song of the human race!) , the excessively overstylized and outcrying attitude by Zulawski. I also thought that the overacting (which wasn't actually overacting but the necessary style for this film was 100 percent Friedkin. 

As expected, "Bug" will not be released theatrical in Germany but on DVD in December. A shame - I think it's one of the best american films in 2006 (I rated it 9/10 - 23/25). Fortunately, It was screened on the "Fantasy Filmfest" (in front of a spiteful laughing #%&*?$ crowd). Though it doesn't seem like a film made for the big screen at the first look, it really need to be seen in this way. The camerawork and the editing were - as you already mentioned indirectly - brillant and I think, the love scene between Ashley Judd and Michael Shannon is one of the best in english language cinema since the famous one in Nicolas Roeg's "Don't look now".

By the way, I didn't like any of Friedkin's films before, especially "The Exorcist" and "Cruising" were terrible experiences two years ago - I disliked both of them a lot. But as I changed by cinematic point of view a bit since and also my opinion on Friedkin (a sympathetic a**h**e, indeed ), I probably owe them a second chance.
