I have just recently watched "Miss Julie", thanks to a friendly americna who send me a DVD copy via mail.
Up until the scene when Julie and Jean sleep together the film is aspiring to greatness, but after that, Strindberg rears his ugly head too much for my tastes, with rather poor textbook psychology and a completely misguided attitude towards women. Though the film has a lot going for it, and I will certainly watch it again in the future. Judging by some of the shots, I think Sjoberg would have also been an excellent silent director. The close-ups are even more stunning than in Hitchcock's films. 
Nevertheless I would give the film a negative rating. Probably C - (on my scale it was a 47 out of 100).
