I found the caracteristics very shallow except for Mikko (the priest), who did quite a good job except for his language. I don't think any priest would use curse words like he did.
The woman seemed to be just a sex addict. I didn't find any deeper interaction between the caracters, just addictive sex.
I liked the relaxed dialogues, Aku Hirviniemi was excellent.
There was not really a proper story or anything deeper. The movie had lots of glanses given between the wife and the guest and even though I normally love just slow camera scenes, in this one it didn't work.
Yet I give 5 stars since I loved the surroundings, the building, the dialogs and Aku Hirviniemi.
The wife and the guest on the contrary weren't credible at all...
