Slovenian Girl (original title: Slovenka, alternate title: A Call Girl) will give you many chills, but it's not a suspense. It just presents the facts. It's not always pretty, it never gets dirty, it has its good sides, some bad too... neutral seems to be the theme.
You'll see her origins, her work, her life, all in a quiet voice. Drama will not become action, pain will not be torment. However, being used to Hollywood, you can expect to be gripping your chair a bit, because all the trappings are there, just not that pre-chewed scenario that would lead you to jump out of your seat.
I can only pull a few negative points: the colors are a bit off, the camera work very simple, and the story a bit sombre. My guess is it's low budget movie that was able to pull off a great performance.
If you don't mind reading subtitles, go for it.
