Glad you liked "Exam."
I didn't think Audition was as good as people make it out to be. It has some gore, and the plot is tweaked, but I was really expecting something wild for all the hype I had heard over the years. Let down.
If you want something different, check out "Bad Boy Bubby." It's a little known Australian film, and wasn't even available on DVD till a few years ago. I had watched it on a converted VHS from a guy I worked with. In fact, we use to give it to all the new hires at the startup I worked at. One person came back and and said they didn't want to work with us. :haha
Anyway, it's different, but awesome.
