I liked the first one and watched this with low expectations because I didn't expect much from a crazed institutionalized sibling. I was wrong. Lisa was brilliant, cunning, and much much smarter than her pining, lovesick brother. A great LFM movie. The sister infiltrates Amanda's life by befriending her and has to bite her tongue while Amanda bad mouths her brother at every turn. This was a great cat and mouse theme. Very well executed. (Have not seen the 2nd one yet)
