The acting is a revelation. [definitional]
This film is almost perfect. It could very easily have gone wrong; it could have made fun of the withdrawn, elderly innocents, or it could have been cynical about them. But its humor is gentle and observant, and its pace is calm and precisely calculated. The acting is a revelation; you will appreciate it, although it is done in Danish. The ironies are not obtrusive; some are sweet, others to be savored.
