This was the fourth Miike film I've seen (Audition, Ichi, Gozu...well 5th if you count his short from Three Extremes) and I think this was by far the most bizarre and disturbing. I'm not squeamish or easily affected by movies so it didn't really disturb me but I can see where it would be disturbing to the average viewer. Miike did manage to hit upon almost every taboo in the books. I'll admit that I did feel somewhat dirty because I got turned on by the opening scene...but hey, it's a just a movie.
Overall I think it was a unique take on the reality TV craze and voyeourism in general. While I didn't like it as much as his other movies that I've seen it's definitely worth checking out.
