Although the screenplay largely relies on two characters talking to each other it should have been more interesting than it was considering one of them was a serial killer.
A never sit still title character is only really challenged by the interchange between the mother (Elina Labourdette) and her grown up 14 year old daughter.
Although it is handled lightly I don't think it works as well as it could have as a comedy. Never boring though and the sailor's dance scene was excellent.
