If you have been a fan of Wallace & Gromit before this you know that there tends to be a lot of slapstick style comedy. This short however takes a turn to the very dark, opening with a murder and ending (for the first time I recall) with the death of the villain. It is much scarier for kids than their previous work. In the making of feature, the producers talked about taking on a more noir style in this film and it shows. I'd be very cautious about showing this to younger kids. The previous 3 Wallace & Gromit shorts are a much safer bet.
