The Other Sister is a thoroughly enjoyable film. Strong performances by Ms. Lewis and Mr. Ribisi as intellectually challenged individuals were very believable, but for those looking for a story that is believable may find this film at times disappointing. Some situations seemed very contrived and the other characters seem at times to be just "add ons". The two other sisters were not well written and Ms. Keaton seemed "a little over the top" although that may well be the case for a mother in her situation. Mr. Skerritt stole the show in my opinion as the solid understanding but sometimes misunderstood father. I did like the The Graduate clips and analogous setup. All in all I enjoyed the movie even though its presentation on such a complex subject seemed simplistic and contrived at times but it did not trivialize and does provide some insights into trials, heartache, and satisfaction of challenged individuals. Two and a half stars.
