For a film with so little action, and so few people, it has a tremendous dialogue and great drama between Pierre and Katja - sometimes a little overdone, but generally the tension is so strong you can't take your eyes from it.
As good as it is, it has its flaws too. Sometimes the journalist really slips off his professional stance which he now and then tries to uphold. I think a real journalist would not do that - as all pros, journalists tend to keep professional, even when doing a job they don't like, or even more so in an unpopular work situation. As a pro and seasoned vet, Pierre should have kept to his professional attitude more.
Likewise, the dialogue goes off the map and then takes its time to get back on track. This is in a way a little tiresome, but also quite intriguing and one of the reasons the film came out so good. A beauty mark so to speak.
This was my first van Gogh film, and I'll be sure to see more of him whenever I can.
