Far from my favorite Bergman, but still a pretty interesting film, it has a great atmospheric feeling that I really liked, and there's this whole sense of haunting thoroughly.
An interesting portrait of a tormented artist, filled with obsession and haunted by appearances and muses; endless nightmares and darkness that end up in madness, in the darkest sad of human emotion, a self-reflection, an endless question. The second half was particularly amazing, accompanied by a great feeling of dread and subtle horror, and Bergman really knows how to create chilling scenes, with shocking imagery and sound (the scene in the cliffs was fantastic and horrifying).
I feel I still missed a lot of what went on, so I may need to revisit this eventually. Liv Ullmann is a treasure.
