It’s exciting to see Shyamalan on such confident footing once more, all these years later.
"The Other Sister'' is shameless in its use of mental retardation as a gimmick, a prop and a plot device. Anyone with any knowledge of retardation is likely to find the film offensive. It treats the characters like cute little performing seals--who always deliver their "retarded'' dialogue with perfect timing and an edge of irony and drama. Their zingers slide out with the precision of sitcom punch lines.
The film stars Juliette Lewis as Carla, a rich San Francisco girl of 17 or 18 who has just returned home after several years in an institution. Her ambition is to train as a veterinarian's assistant. Her father (Tom Skerritt) thinks she should go for it, but her mother (Diane Keaton) is opposed. If there is a convincingly retarded character in the movie, it's the mother. She's borderline hysterical in insisting her daughter is not ready for junior college, dating, dancing, sex, living in her own apartment, or anything else.
In flashbacks to the girl's childhood, we see her crying out, "I don't want her to be retarded!'' Now she doesn't want her to be anything else. Her opposition to any sign of Carla's independence is handled oddly, however. Every once in a while, she has a brief moment of humanity, in which she softens and says sensible things like, "I'll try to see it your way.'' These interludes play suspiciously as if they were inserted into the script to lighten the character and make her less of a harridan. Then it's back to bull-headed denial again.
Carla does eventually get into the local polytechnic, where she makes a friend of Danny (Giovanni Ribisi). The two of them are the butts of some cruel treatment, but Danny has found a haven in the music department, where, he proudly tells Carla, he has a real job: "cleaning the marshmallows out of the tubas.'' That's because at football games students throw marshmallows at the tubas in the marching bands. I am prepared to believe they do that, but not so prepared to believe that something equally cute comes up at every juncture, as when Carla and her mother attend a benefit at a dog shelter and Carla starts barking at the strays and releases them, disrupting a reception. Or when she's garbed in an absurd swan costume for a social event. Or when she and Danny, alone at last, study positions in The Joy of Sex .
