Great Watch, would watch again, and can recommend.
Heather Graham proves mastery of the craft in this beautifully written psych thriller. She embodies the obsession (a more appropriate term than the title) of the character and the ridiculous obsession with food.
Carrie Ann-Moss ("The Matrix": Trinity) shows an equal quality of acting with her character, creating a double helix of psychosis.
If you like psychology based drama, this this will satisfy that hunger for crazy people in normal situations behaving madly.
