The thing that struck me most about Audition was the way I felt after the film had finished. Maybe it was just because I watched it alone, in the dark, isolated from everything else through a big ass pair of headphones....but when I turned it off, I felt like I'd woken up from a nightmare. Thats the kind of impression it leaves on you...
The film actually starts off reasonably slowly, but not in a boring way...more intriguing. The acting is very realistic and the relationship between The father, his son, and Asami, when she comes into the picture, is very convincing. As Aoyama and Asami spend more time together, its easy for the viewer to see that Aoyama's vison is blurred and he can't see what he's getting himself into, its no surprise when Asami disappears.
The remaining part of the film leaves you wanting it to end, but your wanting to see the conclusion which puts you in a situation where you can't get out of watching the horror.
Granted...there is no REAL conclusion to the film, but I was satisfied with the ending...even slightly upset. A terrific horror movie, absolutely nothing like anything from the Western world!
