I'm not qualified to disagree with the glowing reviews of the acting, etc., but I was annoyed by the way the flashbacks were done. I suppose it was a metaphor for what Iris must have been going through.But LOTS of people are slutty or succumb to Alzheimer's. What made Iris noteworthy was her writing. To focus on the former and almost entirely omit the latter is shamelessly manipulative, and it made my girlfriend, who lost a grandparent to Alzheimer's, cry.I suppose the moral of the story is: Don't watch movies; read books instead.
