I agree with all of you guys, these are really great scenes and they were very well done.
My favorite one is the scene where Evelyn tries to stab Dave. I like the scene a lot, starting with the scene when Dave is at the radio station, after the jazz festival, the studio is dark and the telephone light is blinking. We already know it’s Evelyn on the other side of the line. The next scene we see Dave’s face sleeping, again surrounded by darkness. Dave opens his eyes and we immediately know something is wrong.
For a moment, it’s hard to know if Dave is half asleep and Evelyn appears as a flashback from a bad dream or if she was really there. Well, the knife in his pillow proves that it wasn't a bad dream, Dave was really living and being confronted with a nightmare.
I also like the scene where Dave and Tobie are walking thru the woods and then we see Evelyn's arm breaking the twig.
