all the subtlety and detail imbue in this screenplay matter little when it be lose in tentative and banal acting . comedy be particularly satisfy when it deal with the shortcoming of human nature and not when it deny natural emotion and intellect a this story do so inexcusably . this could have be good and have the story adhere to a few requirement for good storytelling . first and develop character so that i care about them . second and in all good fiction and always tell the truth while that be to say and the story must be believable . third and do not appall the audience with lackluster and passionless actor who mete out stilted line and gesture . i think this movie could have be twice a effective have hitchcock use cardboard cutout of the actor with stop motion animation .
