I was a little confused by the ending - after the way she terrorized everyone, it didn't make sense that both she and Baby would completely turn around in an instant. I mean, one minute she is cursing her son-in-law, then Bobby gives her little outburst and she makes a complete turn.
I like the show, but I thought the way they ended this particular episode was kind of lame. Maybe they were trying to show too much at once (I mean the mother-in-law's blind faith in the horoscope, her pushing her will on everyone around her, her interference in her daughters' lives, etc.). They probably could have done a better job with the story if they had kept her for a few episodes and dealt with each aspect of her visit with a different story.
