This movie takes the smoldering talents of Joan Crawford and lets them burn the screen down, right before your eyes...she's utterly convincing as a fairly demented "possessed" lover, torn to pieces by hideous dysfunction. The lowest of lows, and not many highs...
Mildred Pierce laid the template down; Possessed fills the template and makes it its own. What I personally love is the "Hollywood Gothic" aspect, the redolence of that: every frame is steeped in it, every moment is cradled in its embrace. One of those movies that you watch, mouth agape, and whisper to yourself, "Christ, the aesthetics...was the world ever really like that?" Apparently so.
Oh, and for the record - it was a better world.
