Three estranged half-siblings face a family crisis when their horrible mother refuses to leave a bankrupt furniture store. Mother, Couch sports an all-star cast in a surrealist dramedy that leaves many questions purposely unanswered. Strong lead performances by Ewan McGregor and a venomous Ellen Burstyn don’t amount to much in the end. The film evokes the theater of the absurd, with a head-scratching response when the narrative goes bonkers. What begins as relatively straightforward takes a fever dream turn that pushes weird off a cliff. This approach may appeal to the art house cinema crowd but will leave most audiences befuddled.
