Several doctors in this film speculate that Ms. Crawford's character might be suffering from mental illness. Are they right or wrong? This is a big question to be answered in "Possessed" because it seems that somebody here could be BERSERK and might even be a candidate for a STRAIGHTJACKET!
I am a little disappointed that there isn't as much plot-based drama in this film as in MILDRED PIERCE. Mildred Pierce has drama consistently built into the plot whereas this film has a lot of Crawford engaging in dramatics and neuroses rather than more active drama. However this is a more psychologically oriented film (not a noir) and Crawford's acting is believable and solid. Raymond Massey does a good job in the Walter Pidgeon role (or is it Walter Pidgeon in the Raymond Massey role?) You also get a polished jewel of a performance by Stanley Ridges.
Basically a soap opera with a well-done psychology theme, "Possessed" will probably hold your attention due to Crawford's excellent performance. This film is an impressive accomplishment for her.
