No, unfortunately the only films by Richard Linklater I've seen so far are "School of Rock" and "Fast Food Nation". I didn't like both of them very much but I'm sure that Linklater is a great filmmaker and worth to check out. Everything my two friends from Erlangen told me was music in my ears (they were lucky enough to meet him in person on the Munich Film Festival), so in the future I'll watch out for his more interesting works like "Dazed and confused", "Slacker", "Suburbia" and "Before Sunrise" for example. 

Probably the greatest unintentional disadvantage of "Bug" was its distribution which made many believe they were attending a horror film ("By the acclaimed director of "THE EXORCIST"...), which it isn't really. (Though a very disturbing and frightening experience)

Btw, was it realeased theatrical in the US?!

@ justindeimen:

I agree with most of your notes (but your political associations seem a bit, well, bustling to me) and I've had an incredibly amount of interesting thoughts in mind after the screening. So it was pretty hard to write the review which I worked on for almost three weeks. 

I'm looking forward to revisit "The Exorcist" and "Cruising" and probably, the latter will grow on me but I suggest that my opinion on the first will remain the same. It would be most interesting to see "The boys in the band" (still not available on DVD in the US, right?) as one of the main reasons why I disliked "Cruising" were the usual - I thought it to be extremely homophobic and disgustingly striking. So I'm absolutely anxious to see "The boys..." as it probably reveals how Friedkin really deals with homosexuality.
